A study of 1MHz multi-sampling deadbeat control with disturbance compensation for PMSM drive system using FPGA

Abstract

A new digital control method for permanent magnet synchronous motor based on deadbeat control using FPGA based hardware controller is proposed. Adopting FPGA based hardware controller, all the control calculation can be finished within around 1 μ second, which result in the realization of the ideal digital control feedback without any sampling compensation method. In this paper, 1MHz multi-sampling deadbeat control with disturbance compensation method was proposed and compared with the conventional deadbeat control method through simulations and experiments, the advantages of the proposed method was verified.
