摘要 对于具有不确定性的多输入多输出非线性系统,仅用I/O线性化设计方法不能获得好的控制结果。为此,设计了自适应模糊控制器,把I/O线性化方法和自适应模糊控制相结合,构成混合控制器。并将此控制器引入到卫星大角度机动控制系统中,以补偿由系统的不确定性所造成的跟踪误差,从而增强I/O线性化控制器的鲁棒性,最终实现零误差跟踪。 For uncertain multi-input multi-output nonlinear systems,only using an I/O linearization design method can not obtain a good control result.Thus,this paper presents an adaptive fuzzy controller.The combination of I/O linearization method and adaptive fuzzy control constitutes a hybrid controller.And we introduce the hybrid controller into the large angle maneuver control system of a satellite,to compensate for the error caused by the uncertainty of the system tracking,thus increasing the robustness of the I/O linearizing controller.Eventually achieve zero error tracking.
