首先达到MFPCC是基於预测电流控制的电流差检测技术,既不需目前预测电机参数,也不需要反电动势.MFPCC只需要计算定子电流及更新对应於在每个采样周期所施加的开关状态的电流差异.之後,利用计算出的电流差异的假设下,可以预测未来的定子电流,藉此测得定子电流和所计算的电流差.接著定义成本函數以计算在下一次取样时间间隔内的所有可能开关切换狀态下所对应的成本函數值.找出其中最小成本函數值的电压向量,此电压向量所对应的开关切换状态,将在下一个取样时间输出以控制变频器的驱动讯号.

答案

The first MFPCC is based on the current predictive current control difference detection technology,which does not need the prediction parameters of motor,also do not need to counter electromotive force.MFPCC only need to calculate the stator current and update the corresponding current difference in switching state at each sampling period of the applied.Then,using the current difference was calculated under the assumption that the stator current,can predict the future,to the measured stator currents and the computed current difference.Then the cost function to compute all possible switching state of readiness by the cost function values at the sampling time next time interval.Find the minimum cost function values of the voltage vector,the switching state of the voltage vector,will in the next sampling time output to control the driving signal converter.
