摘　　要：动态响应和抗扰动能力是直接转矩控制(DTC)的一项重要指标,文章以内置永磁同步电机(IPMSM)数学模型为平台,提出了IPMSM-DTC系统仿真建模的方法,通过模型分析系统的动态响应和抗扰动能力。利用Matlab/Simulink建立独立的子模块,并对其工作原理和构造方法进行了详细介绍,通过各子模块有机结合构建IPMSM-DTC系统的仿真模型。仿真结果证明了该系统具有较好的动态响应性能以及对负载扰动具有较强的鲁棒性,为后续研究空间电压矢量脉宽调制直接转矩控制系统提供可靠的理论依据。Dynamic response and anti disturbance ability is the direct torque control（ DTC） is an important index,this paper with a inner permanent magnet synchronous motor（ IPMSM） mathematical model for platform proposed IPMSM-DTC system simulation modeling method,through the model analysis of system dynamic response and anti disturbance kinetic energy force. Using Matlab / Simulink to establish an independent sub module,and its working principle and construction method are introduced in detail,and the simulation model of IPMSM-DTC system is constructed by the combination of each sub module. The simulation results showthat the system has good dynamic response performance and robustness to load disturbance. This provides a reliable theoretical basis for the follow-up study of space voltage vector pulse width modulation direct torque control system.
