Study on Torque-compensated MTPA Control with Feedforward Decoupling for IPMSM
In order to improve speed response ability and high-speed operation stability of vehicle built-in IPMSM drive system,a torque feedback compensation control strategy with current feedforward decoupling was proposed for MTPA control.Based on analysis of the motor mathematical model,the strategy was designed to utilize the SVPWM control technology to realize MTPA control.In the comparative MATLAB/Simulink simulation analysis,the use of torque com-pensation adjustment achieved reduction in response time by nearly 40%and effective improvement in high-speed operation stability compared with conventional PI control,verifying the feasibility and effectiveness of the proposed control strategy.
