摘要
根据线性随机系统的包含原理 ,研究系统状态反馈和输出反馈控制器的降阶问题 ,给出了系统控制器降阶的约束和聚集两类条件。以一个 18阶系统降阶反馈控制器的设计为例 ,说明该方法既简化了控制器的结构 ,又不失全阶控制器的主要性能。
The order reduction problem of the system state feedback and output feedback controllers is discussed according to the inclusion principle of linear stochastic systems. Two kinds of conditions, restriction and aggregation, are presented for the controller order reduction. By designing the order reduced feedback controller for an 18-order system as an example, it is shown that the approach can simplify the structure of controllers without losing the main properties of all order controllers.
