✦ Synopsis

In this paper, a stability criterion for nonlinear stochastic multivariable feedback systems is derived. An algorithm is proposed to choose two appropriate dependent weighting matrices of LQG (linear-quadratic-Gaussian) performance index shaped by the inverse LQC method to satisfy the stability criterion. A corresponding robust LQG optimal controller is obtained. No stable, proper, square and minimum phase constraints on the plant are studied.

We propose a novel algorithm to synthesize an H ϱ -optimal observer-based controller for a nonlinear multivariable system. Based on the parametrization of the observer-based controller, a necessary and sufficient condition to achieve robust stability is developed. Moreover, the Nevanlinna᎐Pick inter

## Abstract This paper is concerned with the reliable control problem against actuator failures for a class of uncertain discrete‐time stochastic nonlinear time‐delay systems. The failures of actuators are quantified by a variable varying in a given interval. The stochastic nonlinearities described
