Reduced-Order Observer-Based Controllers and Doubly Coprime Factorizations for Singular Systems
-
摘要: 首先讨论了真镇定带前通的广义系统的最小阶正常观测-控制器的设计问题,然后 基于降阶观测-控制器,明确给出了广义系统双互质分解的一种新的状态空间实现.相应的 控制器参数化可以保证是因果的,因此本文的结果更具实际意义.Abstract: The design problem of minimal order observer-based controllers for properly stabilizing a singular system with direct control feed-through term is discussed, and a design method is given. New state-space formulae of doubly coprime factorizations for singular systems are then presented explicitly. The resultant controller parameterization can be guaranteed to be proper (or causal), thus the results obtained in the present paper are more significant than the previous ones in control applications.
