The H∞-Based Control Strategy to Restrain the Interference to Battery

Abstract

The motor will affect stability and efficiency of battery when it power for motor. The fluctuations of load leads to fluctuations in the torque of the motor which will make the power of battery produce the corresponding fluctuations. Based on the analysis, establish the energy loss model of IPMSM. Based on H∞, finish the control strategy of the almost disturbance decoupling to vehicle power system. The analysis of actual data and the corresponding simulation results shows that the strategy can restrain specific interference that prove it is almost disturbance decoupling.
