Classical controller with intelligent properties for speed control of vector controlled induction motor

This paper presents a classical speed controller (CSC) for vector controlled induction motors. The controller explores the use of a Fuzzy Logic controller in a classical form. The controller combines the advantages of the classical controller and the properties of intelligent controllers. The Fuzzy Logic controller idea is used to obtain the CSC Output equation., whereby the CSC equation is based oil the speed error and its change. The CSC parameters are calculated based oil the motor mechanical equation and a predefined system performance. Once the CSC parameters are obtained, the defined speed performance call be achieved at all operating conditions. The application of the CSC to control the speed of a vector controlled induction motor is presented. Different induction motor ratings are used. Simulation results in all possible operating conditions are presented. Results show that the CSC behaves as all expert controller to provide the predefined speed performance in all possible operating conditions. Based oil the results obtained in this paper, the CSC is expected to become the ultimate solution for high-performance drives of the next generation.
