摘要
在高、中、低电压矢量对矩阵式变换器电机系统直接转矩控制性能影响的基础上,提出了一种新颖的矩阵式变换器电机系统直接转矩控制方法。仿真结果表明该方法结合了高电压矢量动态性能好和中电压矢量正向转矩脉动小的优点,并减小了直接转矩控制失效引起的负向转矩脉动,是矩阵式变换器电机系统理想的控制方法。
A novel direct torque control （DTC） method of matrix converter motor system （MCMS） to improve the performance of the motor system was proposed based on the impact of high, middle and low voltage vectors on the system. Simulation results showed this method was an ideal control method of MCMS which combined the advantage of high voltage vectors ： good dynamic performance and the advantage of middle voltage vectors ： low positive torque ripple and lowers the negative torque ripple when the DTC was disabled.
