A Modi.ed Global Harmony Search Algorithm for Robust PID Controller Tuning

摘要：

The robust turning of proportional-integral-derivative (PID) controller is a hard work,and it is restricted by multiple H∞ performance criteria. The robust PID controller turning is essentially a constrained optimization problem,therefore,a modi.ed global harmony search algorithm (MGHS) is proposed to handle this problem. The MGHS algorithm is a populationbased algorithm,and it updates the worst solution in each iteration so as to improve the quality of all candidate solutions. In this paper,we combine the MGHS and a penalty function method to trade off the objective function value and constraint violations. Experimental results demonstrate that the MGHS can.nd satisfactory controller parameters for robust PID controller tuning.
