Research on DPCC Control Strategy of PMSM Based on LESO
Journal of Physics: Conference Series, 2021 Abstract In permanent magnet synchronous motor control system, the excellent current control effect is very important to the control performance of the system. In order to eliminate the sampling delay in digital control, the deadbeat predictive current control strategy considering sampling delay is proposed. In order to solve the problem
