Analysis and control of the jump modes behavior of 2-D singular systems—Part II: Regular observer and compensator design

This paper considers the problems of regular observer and compensator design for 2-D acceptable singular systems. First, the notions of jump mode reconstructability and jump mode reachability for 2-D acceptable singular systems are proposed. Necessary and sufficient conditions are presented for the jump mode reconstructability and reachability, respectively. Then, we show that there exists a reduced order regular observer for a 2-D acceptable singular system if the system is detectable and jump mode reconstructable, while there exists a reduced order regular compensator for a 2-D acceptable singular system if the system is stabilizable and jump mode reachable.
