Robust Stabilization for a Class of Similar Composite Systems with Uncertainty via Decentralized Output Feedback

讨论了一类具有不确定性的单输入，单输出相似组合系统的鲁棒输出反馈镇定问题·这类组合系统的子系统的一个显著特点是其标称系统的传递函数是严格正实的·在一定假设条件下，这类相似组合系统可以用结构类似于“砰砰”控制器的分散输出反馈控制器鲁棒渐近镇定·最后，把所得到结果用于有源磁旋浮径向旋转运动系统，仿真结果表明了所采用方法的有效性·

The distinguishing features of this class of systems are that their transfer functions of their nominal subsystems are strictly positive real. Under certain assumptions, the similar composite system can be robust asymptotically stabilized by using decentralized output feedback controller. The structure of the controller is similar to the “pang pang” controller. It was discussed that the magnetic bearing spinning systems at length. Its simulation shows the validity.
