A High-Performance Digital Servo Driver for Magnetic Levitation Planar Motor

Abstract:

A new digital DC servo driver based on DSP and FPGA for planar motor was designed in this paper. Current feedback and digital self-tuning PID algorithm control strategy are applied. Switching power amplifier or class D amplifier is the choice of power amplifier. The most prominent characteristic of the servo driver used in planar motor is high efficiency, low temperature drift, small size, fast response, and high-bandwidth. Finally, the performance parameters and power loss parameters of the servo driver are given.
