Rizoug, G. Feld, B. Barbedette and R. Sadoun Chapter 11 The Uses of Artificial Intelligence for Electric Vehicle Control Applications 239 Brahim Gasbaoui and Abdelfatah Nasri Preface Building on MATLAB (the language of technical computing), Simulink provides a platform for engineers to plan, model, design, simulate, test and implement complex electromechanical, dynamic control, signal processing and communication systems. Simulink-Matlab combination is very useful for developing algorithms, GUI assisted creation of block diagrams and realisation of interactive simulation based designs. The eleven chapters of the book demonstrate the power and capabilities of Simulink to solve engineering problems with varied degree of complexity in the virtual environment. The first four chapters provide details of design, analysis, simulation and implementation of flexible AC transmission system devices to control the power variables, multi-component electric circuits, signal transmission through power distribution lines of different kinds and PID/fuzzy logic control of a boom suspension. Details of enhanced capabilities in simulation effects constitute the subject matter of the next three chapters on S-functions for custom made subroutines and bond graph models, development of model and HDL code on FPGA system and harmonic linearization method of non-linear characteristics of modulation techniques. The last four chapters deal with examples of electromagnetic and dynamic systems of thermo- electrical micro hot plate with temperature control circuit, braked railed vehicle wheel slide protection, replacement in a car battery by a hybrid supply of battery and super capacitors and a novel speed control logic for electric vehicle. I hope that both newcomers and professionals in the field would benefit by going through the details given in the above chapters of the book. S.C.
