The design of robust PID controller based on genetic algorithms

In this paper,the design method of PID controller based on the genetic algorithm is applied to these parameter objects,and in this process,genetic algorithm is used for PID parameters optimization while the system robust performance is considered as an important basis for the selection of the objective function.The simulation results show that,due to adding the information of robustness,the rapidity,stability and accuracy requirements are fully met by the system,and the control system shows a very good dynamic and robust performance of robustness.
