Nonfragile Gain-Scheduled Control for Discrete-Time Stochastic Systems with Randomly Occurring Sensor Saturations

Abstract EN

This paper is devoted to tackling the control problem for a class of discrete-time stochastic systems with randomly occurring sensor saturations.

The considered sensor saturation phenomenon is assumed to occur in a random way based on the time-varying Bernoulli distribution with measurable probability in real time.

The aim of the paper is to design a nonfragile gain-scheduled controller with probability-dependent gains which can be achieved by solving a convex optimization problem via semidefinite programming method.

Subsequently, a new kind of probability-dependent Lyapunov functional is proposed in order to derive the controller with less conservatism.

Finally, an illustrative example will demonstrate the effectiveness of our designed procedures.
