摘要:
永磁同步电机传统DTC控制方法由于采用滞环控制方式导致电机转矩和磁链脉动较大,而SVM控制方法基于对转矩和磁链误差的精确补偿从而能够有效降低二者的脉动,但传统SVM控制方法包含了转速和转矩角两个PI调节器,两个调节器的参数设计比较复杂,也直接影响了电机性能.本文从DTC控制转矩角这一本质出发,提出了一种改进的SVM控制方法,通过动态调整转矩角调节器的输出限幅值即可实现对电机转矩的高性能控制,从而省去了复杂的PI参数调试过程.仿真结果验证了所提控制方法的正确性和有效性.
Abstract:
Stator flux linkage and torque ripple are large in traditional direct torque control(DTC)of permanent magnet synchronous motor because of the Hysteresis Control.Space vector modulation(SVM)is based on the precise compensation of the error of stator flux linkage and torque,so it is effective to reduce the ripple.However,two PI regulators are included in traditional SVM method,one is speed regulator and the other is torque regulator.Design of Parameters of the two PI regulators is complex and the motor performance is effected by these Parameters directly.The paper embarks from the nature that DTC control torque angle and presents an improved method of SVM.The motor can be controlled efficiently through dynamically adjusting the output limit value of torque angle regulator.Complex debugging process of the PI parameters can be eliminated in this method.The correctness and validity of the proposed method are verified by simulation result.
