摘要
推导永磁直线电机的简化数学模型,运用Lyapunov稳定性理论设计一个模型参考自适应控制器,最后进行计算机仿真研究。结果表明,与传统PID调节器相比,该方法能使系统具有更好的动态性能及较高的稳态精度,并对电机参数和外界扰动具有很强的鲁棒性。
The simplified mathematical model of the permanent magnet linear motor is deduced in this paper. A model reference adaptive controller is designed by applying the Lyapunov stability theory. Then the controller is evaluated by computer simulation. The results show that the model reference adaptive system (MRAS) is superior to the conventional PID controller in dynamic performance and steady accuracy. The MRAS is robust to the parameter variation and external disturbance.
