Abstract: Considering the nonlinearity and strong coupling of AC induction motor, a co-evolutionary control method is proposed for it，based on this method, distribution function is introduced to regulate the probabilities of individuals production to promote the speed of evolutionary according to the characteristic of control system . Compared with the traditional genetic algorithm, the searching space has been decreased greatly by the method. Furthermore, tested on AC induction motor, the controller in this paper has the traits of high-speed response and small overshoot so on.

Abstract: A model of the AC induction motor, which allows us to analyze all operation modes of motor supplied by the frequency converter, has been developed. A simulation of the inverter of the frequency converter and the AC induction motor interaction on the basis of the developed motor model, using software MATLAB, was performed and a motor regenerative braking mode was investigated. The results of investigation are used for the development of fault protection of the inverter.
