摘要
对间接模型参考自适应控制在无刷直流电机调速系统中的应用做了深入研究,速度控制器采用间接模型参考自适应控制,控制参数采用基于递谁最小二乘法的自适应控制算法,并将间接模型参考自适应控制与常规PI控制进行了比较。结果证明,间接模型参考自适应控制系统有很强的自适应能力和抗负载扰动能力,在系统性能上优于PI控制。
In this paper, the application of the indirect model reference adaptive control(IMRAC) in the Brushless
DC motor is studied. This algorithm is applied to the speed control of an inverter driven permanent magnet
brushless DC motor. The parameter estimation is based on the Recursive Least Square Estimates. IMRAC is
compared to a traditional PI controller. The simulation results show the good adaptive performance and load
disturbance. And the results also show that the performance of IMRAC is superior to that of the traditional PI
control.
