摘要:
为了减小传统直接转矩控制中较大的转矩和磁链波动，并使逆变器开关频率保持恒定，研究了一种基于参考磁链矢量计算的永磁同步电机直接转矩控制方法。从定子磁链矢量的变化所反映出的对转矩和磁链的控制作用考虑，对基于参考磁链矢量计算的直接转矩控制的原理和结构进行了详细地分析和论述。在此基础上，通过转矩方程局部线性化来获取转矩环的控制模型，在线性化过程中的误差进行分析的基础上，研究了转矩环 PI 控制器的参数设计方法。仿真和实验结果验证了所研究控制方法的可行性和有效性
Abstract:
In order to reduce the larger torque and flux ripples of the traditional direct torque control，and obtain the constant inverter switching frequency，an improved direct torque control method of PMSM based on reference flux vector calculation was studied． The principle and structure of the direct torque control with reference flux vector calculation was discussed in-depth by analyzing the control effect of the change of the stator flux vector on the torque and flux． Then the torque loop control model was obtained by partly linearizing the torque equation，and the parameter of the torque loop controller was designed after analyzing the error of the linearization procedure． Finally，the feasibility and validity of the studied control method was verified by the simulation and experiment results．
