A Study of 10 MHz Multi-Sampling Deadbeat Control for PMSM Drive System using USPM Controller

Lately, permanent magnet synchronous motors (PMSMs) have been widely employed in several fields such as in-dustrial equipment, home appliances, and electric vehicles due to their high efficiency and power density. Previous studies have confirmed that PMSM motor drive system with deadbeat control has a superior response to the current reference. In this paper, a universal smart power module (USPM) controller is used to realize a high-performance mo-tor drive system. Because this controller can achieve 50 MHz sampling of the state variables, we proposed a 10 MHz multi-sampling deadbeat control that uses fast sampling ability to follow the load disturbance fluctuation even between carriers and to enhance the robustness to parameter variations. The proposed method was verified through simulations and experiments.
