Experimental Verification of Weighted Moving Average 1MHz Multisampling Deadbeat Control for PMSM

A new digital control method for permanent magnet synchronous motor based on deadbeat control with multisampling method using FPGA based hardware controller is proposed. Adopting FPGA based hardware controller, all the control calculation can be finished within around 800 nano second, which result in the realization of the ideal digital control feedback without any sampling compensation method, and superior transient characteristics can be obtained. In this paper, weighted moving average 1MHz multisampling deadbeat control was proposed and compared with the conventional deadbeat control method through simulations and experiments. The advantages of the proposed method was verified.
