Abstract
In this paper, the discretetime control of decentralized continuoustime systems, which have approximate decentralized fixed modes, is studied. It is shown that under certain conditions, discretetime controllers can improve the overall performance of the decentralized control system, when a linear timeinvariant continuoustime controller is ineffective. In order to obtain these conditions, a quantitative measure for different types of approximate fixed modes in a decentralized system is given. In this case, it is shown that discretetime zeroorder hold (ZOH) controllers, and in particular, that generalized sampleddata hold functions (GSHF), can significantly improve the overall performance of the resultant closedloop system. The proposed sampleddata controller is, in fact, a linear timevarying controller for the continuoustime system.
