1MHz variable sampling deadbeat control for PM motor using FPGA

A new digital control method for permanent magnet synchronous motor based on deadbeat control using FPGA based hardware controller is proposed. Using the discrete time model of PMSM, the deadbeat control law is derived using 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 and experiments.
