Precise torque control for interior permanent magnet synchronous motor using FPGA based hardware controller

Abstract

A new digital control method for permanent magnet synchronous motor based on deadbeat control and FPGA based hardware controller is proposed. Using the discrete time model of PMSM, deadbeat control law is derived via a model inverse solution. The superior calculation capability of FPGA realize the ideal digital control feedback system without any sampling compensation method. The verification of the proposed method were carried out through simulations.
