| 中文摘要 |
| 研究了含未知输入的广义系统的输入解耦观测器设计问题. 在系统脉冲能控的条件下通过系统输入-状态对的非奇异变换, 把此问题等价地转化为正常状态空间系统的相应问题. 用大家熟知的方法设计正常状态空间系统的观测器, 从而得到广义系统的输入解耦观测器. 然后用广义系统的观测器状态和系统输出的线性组合渐近估计系统的状态与未知输入. |
| 英文摘要 |
| The problem of input decoupled observer design for singular linear systems with unknown input is discussed. When the system is impulsively controllable, an equivalent problem for standard state space systems is derived from nonsingular transformation of input-state for systems. An observer of standard state space systems is designed by using well-known techniques, so the input decoupled observer of the singular linear systems is obtained. Finally the state and unknown input of the singular linear systems are asymptotically estimated using the state of the observer and outputs of the systems. |
