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.
