【摘要】 针对无轴承异步电机多变量、非线性、强耦合的特点,本文将自抗扰控制器技术应用于无轴承异步电机的空间电压矢量调制的直接转矩控制(SVM-DTC)系统中,构建了基于自抗扰技术的无轴承异步电机SVM-DTC系统,通过对转子磁链的辨识,实现对定子磁链、气隙磁链的辨识,并用自抗扰控制器替代传统的PID调节器,解决了转速的超调问题。仿真结果表明,系统具有较好的动态性能,对负载扰动、电动机参数变化都有较强的鲁棒性。
【Abstract】 In allusion to the characteristic of multi-variable,nonlinear and high coupling of bearingless induction motor,direct torque control system with space vector modulation for bearingless induction motor is built by using active disturbance rejection controller(ADRC)technology.The stator flux and air-gap flux are realized through the rotor flux identification.The problem of speed overshoot is solved by using active disturbance rejection controller insteading of the traditional PID controller.The simulation results show that the system has good dynamic performance,and also has a strong robustness for load disturbance and motor parameter variation.
