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 The decoupling control strategy is used to control the six degrees of freedom rigid rotor active magnetic bearings (AMB). The nonlinear feedback controller is designed by using the state feedback linearization method based on inverse system theory. The AMB, a multivariable, strongly coupled and nonlinear system, is decomposed into six univariate uncoupled linear subsystems and the linear subsystems are synthesized. The simulation shows that this control strategy achieves dynamic decoupling between degrees of freedom and the dynamic performance of the system is obviously improved compared with the traditional PID control method
