Design for Properly Stabilizing Normal Decentralized Compensators of Descriptor Systems
Zhi Wei GAO;Xian Lai WANG;Guang Quan LI
Systems Engineering - Theory & Practice    1999, 19 (1): 1-8.   DOI: 10.12011/1000-6788(1999)1-1
Abstract1197)      PDF(pc) (199KB)(763)       Save
In this paper, a concurrent design method for properly stabilizing normal decentralized compensators of descriptor decentralized systems with direct control feedthrough is proposed. This concurrent design method gives the same order for each compensator among all the control stations, and the shortcoming of the sequential design method before having very high compensators' orders for large scale systems is overcome. So the design method obtained here is very significant both in theory and in practice.
