摘　　要：研究一种矿用磁链、转速双闭环控制的异步电机矢量控制系统,在传统矢量控制中的PI调节器中引入转矩环,并对SVPWM工作原理进行分析。通过仿真软件MATLAB建立异步电机矢量控制的模型,分析系统空载、带载运行过程中的电流、转矩、转速等状态量。仿真结果表明设计的系统能有效抑制负载的扰动,实现恒流升速,稳态时能保证电机稳速运行。A kind of asynchronous motor loss control system with flux and speed double closed-loop control is studied.The torque loop is introduced into the PI regulator in the traditional vector control,and the working principle of SVPWM is analyzed.Through the simulation software MATLAB,the vector control model of induction motor is established,and the current,torque,speed and other state variables in the process of no-load and on load operation are analyzed.The simulation results show that the designed system can effectively suppress the load disturbance,realize constant current speed up,and ensure the steady speed operation of the motor in steady state.
