Abstract

Based on the mathematical model of the permanent-magnet synchronous–motor (PMSM), a PMSM vector control system model wasestablished in VisSim5.0. The isolated functional blocks, such as PMSM block, controller block, phase voltage block, coordinate transform block, sinusoidal pulse-width-modulation(SPWM) block, speed controller block, etc., were modeled. By the organic combination of these blocks and abundant components in VisSim5.0, the control system model of PMSM could be established easily. In the double loop of control system, a PI controller is adopted in the speed loop and a vector controller is adopted in the current loop. The validity is testified by the simulation results and other control strategies can be applied to the system to testify their rationality. This novel method offers a new thoughtway for designing and debugging actual motors.
