Research Grant of the National University Research Council (CNCSIS), Type A, no. GR76 / 23.05.2007, CNCSIS code 366, Title:

Development of new fuzzy controller structures for embedded systems using Iterative Feedback Tuning algorithms. Director: Prof.dr.eng.

Radu-Emil Precup (grant value for 2007:

31,600 RON)

Fuzzy control is one particular case of nonlinear control techniques, however it is convenient and relatively easily understandable. Fuzzy controllers are usually developed heuristically, and the evident necessity for systematic development methods of these controllers has not been covered till now. The Iterative Feedback Tuning (IFT) technique must not be connected to the modelling phase, present in the majority of controller tuning techniques, making it usable in control of complex plants in embedded and mechatronic systems applications. The project aim, development of new fuzzy controller structures using IFT algorithms accompanied by the development of dedicated software, contributes to the offer of systematic approaches.

The developed controller structures and software were tested generally in control of servo systems with focus on different categories of plants where the problem of adaptation to the environment is set. The experiments performed highlight the control system performance enhancement. The project is baked up by the previous experience of the research team in the development of control systems meant for several classes of plants and in the derivation of some theoretical and practical issues in fuzzy control. Part of project results is obtained in close cooperation with well acknowledged research teams from Hungary.

More then 10 papers were presented at Conferences and published in Proceedings and Journals.

Romanian-Hungarian Session of Scientific and Technologic Co-operation, signed in Budapest, nov. 2005, Appendix II, crt.no. 35 ID no.17) Nowadays computational intelligence theory and techniques and Intelligent Systems are in the trend and focus of research interest. The co-operation during 2006 has embraced and oriented on new Intelligent and fuzzy control solutions and new fuzzy – mathematic solutions. The Intelligent Control solutions represent particular cases of nonlinear control techniques, which are often developed heuristically. There is a necessity for systematic analysis and development methods of fuzzy and intelligent controllers, necessity that needs to be covered.

The domain refers to the development of new fuzzy and intelligent control structures and design techniques that employ also the parametric sensitivity analysis of certain classes of fuzzy control systems. Several shortcomings appear with respect to the Mamdani and Takagi-Sugeno fuzzy controllers and to the intelligent controllers containing fuzzy information processing techniques. This justifies the efforts of the two research teams to contribute to a better systematic application oriented approach to the field. The mathematical processing of input and output signals oriented to complex control systems is investigated.

The original fuzzy and intelligent control structures to be developed within the framework of this co-operation are based on the experience of the two teams, unified through this project. The obtained results will be tested in several control applications.

The project is based on previous experiences of the two research teams in both the development of fuzzy control structures dedicated to several classes of plants and the theoretical and practical developments in the field of fuzzy systems. Since the behaviour of such systems depends highly on the underlying logical and/or aggregation operators, the related and internationally appreciated results of some team members provide an essential and sound basis for the planned studies.

The two teams co-organize annually the Romanian- Hungarian Symposiums on Applied Computational Intelligence (SACI), in Timisoara, destined to the exchange of research results in the field.

The proposed project has the research theme, goal and objectives associated to the priority research domains at international level, researches regarding the control of new wind aggregates structures with vertical axis for conversion of renewable energies, with turbine self limiting blades, with non-regulated

(7)

position. The thematic area concerns the increase of the usage degree of wind energy conversion systems as a non-pollutant energy source, conducting to the reducing of carbon emissions and pollution due to the usage of non-ecological resources (coal/gases/oil energy plants), highly pollutant, in concordance to the global trend of ecologic energy production. The scientific importance and the fundamental research character of the proposed grant resides from the fact that the researches regard a scientific domain of a real actual interest, the usage of vertical axis wind turbines with non regulated pitch blades and without limiting (h-dariues, etc), with permanent magnet synchronous machines, having controlled rotation through the load, operating optimally, with variable rotation, usable in urban space (roof-top wind generators). The researches are extremely opportune and focused towards the cost reduction, the performances and efficiency increase, the repayment time period reduction. All those will become possible due to new innovative solutions, among them subscribing the one forecasted within grant researches regarding new elements and structures of the conversion line of wind energy into electrical energy (the elimination of the gear- box, new generator constructions and frequency converters) and respectively new structures and control methods for wind aggregates. The scientific importance is sustained by the new, original proposed solutions, opening the means of effective applicability in the power energy domain, but not only.

Assoc. Prof. dr. eng. Ioan Filip, Financial value: 15,000 RON

The design and synthesis of new control strategies based on neural networks, assuring higher control quality indicators, superior to the ones existing on the market, and their implementation on an informational support, in the actual trend of increased control process complexity, consists into an important component of the technological progress imposed by the informational society with a direct impact on the automatic control domain.

The synthesis of new neural control solutions, particularized at the synchronous generators excitation control system, together with the completion of researches regarding the solving of certain issues related to the embedded software implementation on dedicated hardware such as the signal processor, consists into the main goal of the proposed project. In the context of the considered

application regarding the synchronous generator excitation command system, the starting point of the research is represented by the identification of mathematical models of synchronous generator based on neural networks (considering several functioning regimes), suitable at simulation studies for the assisting of neural networks controllers design. There are taken into consideration two control strategies: one based on recurrent neural network having added at the final neuron an on-line bias adapting mechanism, respectively a strategy based on ADALINE neural model. The both control structures will be designed, synthesized and tested through simulation scenarios specific to synchronous generators functioning regimes. The last stage is represented by the solving of issues regarding software implementation on the hardware support delivered by a digital signal processor, taking into consideration the development of a Matlab toolbox, thus implementing modularly and flexibly the functionalities of the control structures based on neural networks, assuring rapid code portability into a high level programming language.

2006 Automotive Electric Actuation Technologies (AEAT); UPT Scientific coordinator: Prof.dr.eng. G. D. Andreescu (financial value for 2007: 64,000 lei)

The goal is to develop and propose novel electrical actuators with power electronics and control systems for various functions in automobiles on 42Vdc power bus such as: starter/alternator in hybrid electric or electric vehicles; active steering, steering and braking by wire, climate control, independent valve actuation, active suspension damping, etc., need - for comfort improvement, a reasonable energy consumption and robust response. Now, after the first 42Vdc mild hybrid electric Toyota Crown Royal has become commercial in 2002, there is world-wide interest and effort to introduce more and improve power electronic controlled actuators on automobiles.

The project is aiming at the following objectives:

• To develop and validate a 42Vdc battery model and an efficient battery state estimator in order to optimally manage the energy consumption and storage on board of automobiles

• To propose a new power electronics control system for the claw-pole rotor alternator capable to work either at 14Vdc or 42Vdc for more power

• To develop better PMSM actuators and their advanced digital sensorless control with redundancy for active steering, steering-by-wire and electric braking-by-wire

• To develop new linear electric actuators for independent electric valve and active suspension damping control by power electronics for less peak power and energy consumption

• To investigate a novel starter/alternator configuration (Biaxial Excitation Generator for Automobiles-BEGA) and its control, characterized by very large constant power speed range, very low voltage regulation, good efficiency

• To propose and realize innovative small brushless electric actuators (less than 50W at 14/42Vdc) with low-cost electronic supply and control for various automotive accessories, such as: windshield wipers, window lifts, throttle plate control, positioning systems for lights, seats and rear mirrors, fuel injectors, cooling fans, blowers for HVAC, etc., as well as variable-speed pumps for oil, fuel and water.

In 2007 the main activity and results were to realize experimental models and to do preliminary experimental tests for all our objectives.

International cooperation in the field with the Aalborg University, Institute of Energy Technology, Denmark, included the mobility of Prof.dr.eng. Gheorghe-Daniel Andreescu as a visiting professor for 2 weeks.
