Design of Cascade Pl Controller for Induction Motor Drives using Genetic Algorithm

유전자 알고리즘을 이용한 유도전동기 Cascade PI 제어기 설계

In this paper, we describe a design procedure for cascade controller for induction motor drives based on Genetic Algorithms(GAs). Most electric drives have two separate controllers for current and speed control, which are in general designed in two consecutive steps(firstly the current controller and then the speed controller). We search simultaneously for the couple of discrete anti-windup controllers achieving the optimal compromise of weighted cost and performance indices related to both current and speed responses.
