Design of Speed Controller for Permananent Magnet Synchronous Motor Drive Using Genetic Algorithm Based Lower Order System Modelling

Abstract

Problem statement:In this study, a Model Order Reduction (MOR) method is proposed for reducing higher order system into lower order system. Speed controller design is carried out to the lower order system by Genetic Algorithm (GA) approach and this controller is used to higher order system. Approach: This study is used to find a solution to a given objective function employing different procedures and computational techniques. The problem area chosen is that of lower order system modelling used in design of speed controller for Permananent Magnet Synchronous Motor (PMSM) drive. Results: Genetic Algorithm obtains a better controller values that reflects the characteristics of the original higher order system and the performance evaluated using this method are compared with the existing approximation method. Conclusion: Performance of this Speed controller has been verified through Simulation using MATLAB package.
