摘要
针对永磁同步电机(PMSM)数学模型中的非线性耦合,采用反步设计方法设计一个非线性控制器。该控制器能使伺服系统的转速、电流能够完全跟踪给定而不受非线性因素的影响。然后,利用Lyapunov稳定性理论和Barbalat引理证明了反步控制器的稳定性。最后,根据所设计的控制器搭建实验平台,实验结果显示伺服系统的转速和电流具有很好的跟踪性能和抗干扰性能。
Pointing at the nonlinearities coupling of permanent magnet synchronous motor（PMSM）math model, a nonlinear controller using backstepping design method was designed. The controller could make the errors of speed and current tend to zero without the negative effects of nonlinearities.Then, testified the stability of the controller by Lyapunov stability theory and Barbalat lemma. Finally, built an experiment platform and the results indicate that the speed and current could track the setpoint very well and have strong ability to restrain perturbations.
