Lately, permanent magnet synchronous motors (PMSMs) have been widely employed in several fields such as industrial 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 motor drive system. Because this controller can achieve 50MHz sampling of the state variables, we proposed a 10MHz 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.
