| 摘 要： | 根据现代非线性理论研究了三相永磁式步进电动机的非线性动力学，研究表明在高频情况下系统会经历一个动态的Hopf分叉．同时提出了解决三相永磁式步进电动机不稳定性的控制方法，设计了非线性鲁棒控制器，阐明了电动机参数不确定的情况下，如何使系统稳定并具有令人满意的性能．

| Abstract: | The nonlinear dynamics of a three-phase permanent magnet stepmotor is investigated by means of modern nonlinear theory. The investigation shows that the system experiences a dynamic Hopf bifurcation at high frequencies. The method of solving the instability of a three-phase permanent magnet stepmotor is advanced and a nonlinear robust controller is designed. |
