提出了一种适用于要求高扭矩/功率精度和快速动态响应的宽转速范围内永磁电机的转矩控制方法。利用电机参数是非线性的，并且随着直流和交流点的变化而显著变化的事实，生成了一个新的最优工作平面。该工作平面结合了最大每安培扭矩(Mtpa)曲线、电流限制圆和最大每伏扭矩(MTPV)曲线、电压限制以及在非线性参数变化下的扭矩计算。结果，生成了新的前馈表，充分利用了测量的电机参数。围绕前馈工作台构建的新型扭矩和磁链调节器提供快速的动态响应和准确的稳态扭矩/功率生产。所提出的控制器已在燃料电池汽车项目中使用的105kW IPM电动驱动上实现并成功地进行了测试。
This paper proposes a torque control method for interior permanent-magnet (IPM) motors operating in a wide speed range requiring high torque/power accuracy and a fast dynamic response. Using the fact that the motor parameters are nonlinear and significantly vary with direct and quadrature current operating points, a new optimal operating plane is generated. This operating plane combines the maximum torque per ampere (MTPA) curve, current limit circle, and maximum torque per volt (MTPV) curve, voltage limitations, and torque calculation under the nonlinear parameter variations. As a result, new feedforward tables are generated, which make full use of measured motor parameters. The new torque and flux regulators built around the feedforward tables provide a fast dynamic response and accurate steady-state torque/power production. The proposed controller was implemented and successfully tested on a 105-kW IPM motor electric drive used in a fuel-cell vehicle program.
