| 摘 要： | 运用解耦控制策略对六自由度刚性转子主动磁悬浮轴承（ＡＭＢ）进行控制，应用基于逆系统理论的状态反馈线性化方法，设计出非线性控制器。将ＡＭＢ这一多变量、强耦合及非线性的系统，分解为６个单变量无耦合的线性子系统，并对线性子系统进行了综合。仿真表明，此控制策略实现了各自由度之间的动态解耦，系统的动态性能较传统的ＰＩＤ控制方法有明显的提高。

| Abstract: | A decoupling control approach has been developed for a nonlinear system of a six degree of freedom rotor supported by active magnetic bearings. A nonlinear controller based on dynamic feedback linearization is designed such that the strongly coupled rotor motion is reduced to six decoupled normalization linear subsystems including five rotor displacements and its speed. The linearized system improves the transient response of the system. Satisfactory performance of the decoupled system is obtained. |
