PID Controller Based on Genetic Algorithm and its Application

This paper gives a simple introduction for genetic algorithm and PID controller. A method is proposed based on genetic algorithm （GA）, which uses genetic algorithm to optimize the PID parameters. The Optimization process is mainly introduced. The paper simulates and compares several parameters setting methods through an example and the result shows that the method based on GA is superior to current methods. At last, the algorithm is applied into the wind speed control in the air explosives production line and the anticipative effect is obtained.
