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

Lately, permanent magnet synchronous mo-tors (PMSMs) have been widely used in many fields such as industrial equipment, home appliances, and electric vehicles due to its high efficiency and high power density. From previous studies, it has been 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. Since this controller can achieve 50 MHz sampling of the state variables, a 10 MHz multi-sampling deadbeat control is proposed that uses fast sampling ability to follow the fluctuation of the load disturbance even between carriers, verifications are carried out through simulations and experiments.
