| 中文摘要 |
| 研究了含未知输入的非方广义系统的有限时间输入解耦观测器设计问题, 在一定条件下基于非方广义系统的结构特征, 引入一个输入–状态对的非奇异转换, 把含未知输入的非方广义系统等价地转化为输入已知的正常状态空间系统. 用传统的设计正常状态空间系统观测器的方法去构造含未知输入的非方广义系统的未知输入观测器, 并给出了观测器存在的充分条件, 由此得出了有限时间观测器的设计步骤. |
| 英文摘要 |
| The problem of input decoupled observer design in finite time for nonsquare descriptor systems with unknown input is investigated. Based on the constructive characteristics of the systems, an input-state pair of descriptor systems is introduced, which transforms the nonsquare descriptor system with unknown input into a standard state-space system where the input is known. It provides a new and simple method to construct unknown input observer for nonsquare descriptor system by using some traditional methods for standard state-space systems. The sufficient conditions for the existence of unknown input observer for nonsquare descriptor system are also given. From these, a unified design procedure for the finite time observer is derived. |
