✦ Synopsis

A state-space-based design method is developed to construct strongly stabilizing controllers for a class of MIMO plants. The problem is reduced to solving an algebraic Riccati equation (ARE) which appears in the solution of a two-block H problem. Strongly stabilizing controllers designed here are of the same order as the plant. Two sets of "nite-dimensional strongly stabilizing controllers are parameterized in terms of linear fractional transformations. Further optimization guidelines are given to "nd stable H controllers from these parameterizations. Stability robustness margins, with respect to coprime factor uncertainties, are determined for the controllers designed from the proposed method.

In this paper, the design of rational X" suboptimal controllers is studied for possibly unstable SISO infinite dimensional plants. In reference 1, it was shown that all X" controllers can be expressed in terms of (i) inner and outer parts of the plant, (ii) a finite dimensional spectral factor obtai

The aim of this article is to present some new stability sufficient conditions for discrete-time nonlinear systems. It shows how to use nonnegative semi-definite functions as Lyapunov functions instead of positive definite ones for studying the stability of a given system. Several examples and some
