摘要
提出了将模型参考自适应技术应用于永磁同步电机无速度传感器控制系统中。根据永磁同步电机的数学模型,设计了一个基于模型参考自适应的状态观测器估算电机转子速度,并对系统的稳定性进行分析,在Simulink软件中建立相应的仿真模型。仿真结果表明:该控制系统可以较准确地追踪转速,具有良好的动态性能和鲁棒性。
The model reference adaptive technique is applied in the sensorless control system of PMSM. On the basis of PMSM mathematical model, a MRAS observer is designed to estimate the motor rotor speed, the stability of system is analyzed and the simulation model is built by Simulink. The simulation results show that the system tracks the motor speed accurately, and it has better dynamic performance and strong robustness.
