基于滑模变结构的永磁同步电机(PMSM)直接转矩控制
PMSM DTC Based on Sliding Mode Variable Structure
摘要
Abstract
In order to solve the problems of stator flux and the electromagnetic torque ripples which are larger in traditional PMSM direct torque control system,exponential reaching law sliding mode variable parameter controller and variable parameter PI speed controllers were used to replace hysteresis comparator and PI speed regulator,and the direct torque control was conbined with space vector modulation technology to build the improved PMSM direct torque control system. simulation results show that the new system can effectively reduce the torque ripple and keep stability of the inverter switch frequency,while maintaining the direct torque control torque response fast and strong robustness,excellent dynamic performance.关键词
