An Adaptive Control SystemBased on Brushless DC Motor and Its Application

针对因负载扰动而导致无刷直流电机系统输出不稳定的问题,设计了基于Lyapunov稳定性理论的模型参考自适应控制器。并与传统PID控制器进行比较。实验结果表明,该控制器能极大地提高系统的鲁棒性,在抗负载扰动上明显优于传统PID控制器,在改善因负载扰动而导致系统输出不稳定上具有重要意义。

The model reference adaptive controller based on Lyapunov stability theory is designed to solve the problem of output instability of brushless DC motor system caused by load disturbance.And compared with the traditional PID controller.Experimental results show that the controller can greatly improve the robustness of the system,and is significantly better than the traditional PID controller in resisting load disturbance,which is of great significance in improving the system output instability caused by load disturbance.
