摘　　要：为提高车用内置式永磁同步电机(IPMSM)驱动系统的速度响应能力和高速状态的运行抗干扰性,提出了以最大转矩比电流(MTPA)控制为基础,采用带电流前馈解耦的反馈补偿控制策略。在分析电机的数学模型的基础上,借助电流空间矢量脉宽调制(SVPWM)控制技术实现MTPA控制。在MATLAB/Simulink仿真对比分析中,使用转矩补偿调节相比传统PI控制可使响应时间缩短近40%,并有效提高高速运行时的抗干扰性,验证了所提出的控制策略的可行性和有效性。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 compensation 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.
