针对永磁同步电机提出采用模型参考自适应控制策略进行伺服定位控制仿真研究;建立李雅普诺夫函数,设计了由控制对象的输入和输出构成的模型参考自适应控制规律,该控制策略能够解决非线性、时变系统带来的不确定性,提高伺服电机的位置控制性能;仿真研究结果表明:该自适应律能以优异的性能完成定位跟踪任务,控制效果较好。

In view of the permanent magnet synchronous motor, the model reference adaptive control strategy is put forward to carry out the simulation study of servo positioning control. We establish a lyapunov function, and the design is composed of control object input and output of the model reference adaptive control law, and the control strategy can solve the uncertainty of the problems of nonlinear, time- varying system, and improve the position of the servo motor control performance. The simulation results show that the adaptive law can perform the task of positioning tracking with excellent performance, and the control effect is better.
