Application of Fuzzy Adaptive PID Control in Magnetic Suspension Test Vehicle Model

This paper takes the magnetic suspension test vehicle model as the research obj ect and establishes the dynamic model of single electromagnet. In order to overcome the large hysteresis caused by inductance change and improve the dynamic response performance, a current loop is added to the system. A fuzzy adaptive PID controller is designed for the electromagnet model with strong nonlinearity and model uncertainty. Simulation and experiment demonstrate that the controller can markedly improve the control performance of the magnetic suspension test vehicle model system, make the overshoot of the system smaller, and have better anti-interference ability and faster response speed.
