Abstract
Aiming at the parameter tuning of digital PID controller, this paper introduces a method of tuning PID parameters based on differential evolution algorithm, and writes M script file in MATLAB environment for computer simulation experiment. The results show that after the controller parameters are optimized and tuned by this method, the system response speed is faster, the time to reach steady state is shorter, and the parameter tuning speed and accuracy have been significantly improved.
