摘　　要：针对一类具有线性不可测量状态的非线性系统,基于状态反馈稳定控制器,利用不变流形和滑模变结构控制技术设计了动态输出反馈镇定控制器.这类控制器的结构类似于系统的状态反馈稳定控制器,在较简单的假定条件下,能够保证被控系统的状态得到渐近镇定.仿真算例表明该动态输出反馈控制器具有较强的镇定能力.By using the invariant manifold and sliding mode variable structure technique,dynamic output feedback stabilization controllers are proposed,based on known state feedback controllers for a class of nonlinear systems with linear unmeasured states.The structures of controllers designed are similar to that of known state feedback controllers.The designed controllers can force the states of controlled systems to be asymptotically stabilized under some simply mathematic conditions.A simulation example shows the better stability of the proposed controllers.
