Abstract PID control is the most widely used control method in rotor system of an active magnetic bearing (AMB) high-speed motor. However, it is difficult to find three proper parameters for PID controllers. In order to reduce the difficulty of PID parameters tuning, an internal model control (IMC) was combined with PID control to design an IMC-PID controller, which transforms the tuning process of three parameters into one. Then, the influences of the only parameter on the stability, anti-interference ability, maximum vibration amplitude and critical speed of rotor system were analyzed, and the rules for its selection were clarified. At last, the designed IMC-PID controller was simulated on a single-degree-of-freedom magnetically levitated system and an AMB high-speed motor rotor system, and the related experiments were carried out on an AMB high-speed motor platform. Both simulation and experimental results show that IMC-PID control has good control performance and strong robustness.
