Abstract

In modern control system, PID, proportional-integral-derivative control, is normally used according to its straightforward structure, strong adaptability, and easy manipulation. However, in the real world, traditional PID controller might meet issues like low stability, weak anti-interference ability, and unsatisfying response capability. With the aim of solving the mentioned problems, fuzzy method is be applied into PID controlling and anti-interference technology is added as well. Firstly, according to the original physical model, mathematical model is established, and the transfer function is calculated out by applying appropriate motor parameters. Secondly, the methodology of fuzzy control is added into the servo motor system so self-adaptive PID controller is achieved. Finally, a concise comparison of the simulation results is carried out and our proposed fuzzy PID is proved to perform much better than the traditional one.
