摘要
由于电机定转子参数的变化,利用一般的转子磁链对转速进行估算,将导致不能得到准确的结果。这里采用积分型转子磁链的参考和可调模型构建出一个基于MRAS的异步电机无速度传感器的矢量控制模型。该模型提高了矢量控制系统的动态性能并利用MATLAB/SIMULINK进行了异步电机无速度传感器矢量控制系统的仿真,验证了文中所采用的模型参考自适应的速度估算方法的可行性以及对参数误差的鲁棒性。
Due to the changes in the parameters of the motor stator and rotor,the rotor speed estimated by the general rotor flux is unable to obtain the accurate result.We adopt the integral rotor flux reference and adjustable model to construct a speed sensorless vector control model based on MRAS.The model improves the dynamic performance of the vector control system.The simulation of speed sensorless vector control of IM by MATLAB/SIMULINK verify the feasibility and the robustness to parameter error of the MRAS method.
