In this paper, we consider the problem of finding a time-varying controller which can stabilize a decentralized discrete-time system. In continuous-time, it was already known that time-varying decentralized controllers can achieve stabilization in cases where time-invariant decentralized controllers cannot. This paper works out the details for the discrete-time case.
We study decentralized stabilization of discrete-time linear time invariant (LTI) systems subject to actuator saturation, using LTI controllers. The requirement of stabilization under both saturation constraints and decentralization impose obvious necessary conditions on the open-loop plant, namely that its eigenvalues are in the closed unit disk and further that the eigenvalues on the unit circle...
In this paper we study global stabilization of a class of nonlinear uncertain systems while decoupling the output from external disturbances to any specified degree of accuracy. The class of nonlinear systems considered could be viewed as a generalization of uniform rank multivariable linear systems which have the property that all their infinite zeros are of the same order. Although the plants considered...
