Research on control strategy of suppressing disturbance of electric vehicle driving motor

The state of the electric vehicle under the state of motion, the stability of its operating status, efficiency will be affected by the motor running status. The load disturbance of the motor will cause the output torque to fluctuate, which will cause the vehicle battery to generate the corresponding fluctuation. Based on the above analysis, through the establishment of permanent magnet synchronous motor loss fluctuations in the general model, based on the H

control theory, complete vehicle power supply system almost interference decoupling control strategy. Through the analysis of the actual data, and the corresponding simulation results show that the control strategy to achieve a specific interference suppression, proved that the control strategy can be set almost interference decoupling.
