摘要：Using magnetic levitation technology to implement a reference signal can avoid fluid mechanical surge and better control the movement of motorized spindle-mounted cutting tools. Magnetic levitation has the advantages of no friction, no mechanical wear, and high efficiency. In this paper, the performance of axial trajectory tracking control of active magnetic bearings with a classical proportional-integral-derivative (PID) controller is studied. First, the principles of trajectory tracking with an active magnetic bearing system are expounded, and the mechatronics models of such a system are established. Then, a PID controller is designed and trajectory tracking performance using different reference signals is verified by simulation and experiment. The results show that PID-based control of magnetic bearings can meet the requirements of tracking position control. In the experiments, the tracking errors were all within 18 mu m in the rotating state.
