改进的永磁同步电机直接转矩控制系统研究
Research on Improved Direct Torque Control System of Permanent Magnet Synchronous Motor
摘要
Abstract
The inverter power supply mode,control strategy and pulse width modulation algorithm for permanent magnet synchronous motor direct torque control system were improved. To solve the flux linkage ripple and the torque instability in DTC system,the traditional DTC system′s switching table and hysteresis comparator were replaced by space vector pulse width modulation. DTC system supplied with three-level inverter was set up. The improved three-level inverter was used to replace the two-level inverter,and the principle of symmetry was used to improve the SVPWM algorithm. In addition,the improved speed regulator based on ADRC was designed. Simulation results verify the effectiveness of this control strategy.关键词
