摘要: 针对常规的永磁同步电机预测转矩控制方法存在计算量大、需要设计权重因子等缺点,提出了一种改进的永磁同步电机无权重因子预测转矩控制方法.该方法在静止坐标系上执行预测控制,避免了大量的坐标变换运算,从而简化了预测过程.将转矩控制误差和定子磁链控制误差转化为标幺值,并基于标幺值提出了一种新的目标函数,消除权重因子的影响.仿真结果表明,该方法的控制效果优于常规预测转矩控制方法,且不需要进行坐标变换运算和权重因子设计,从而简化了系统的设计过程.Abstract: The disadvantages of the conventional predictive torque control method for permanent magnet synchronous motor are large calculation amount and the requirement of designing weighting factor, an improved predictive torque control method for permanent magnet synchronous motor without weighting factor was proposed.The method performed predictive control on a stationary coordinate system, avoiding a large number of coordinate transformation operations,thereby simplifying the prediction process.The torque control error and the flux control error were converted into a standard value, and a new objective function was proposed based on the standard value to eliminate the influence of the weighting factor. The simulation results showed that the control effect of the method was better than that of the conventional predictive torque control method,and the system design process was simplified without the coordinate transformation operation and weighting factor design.
