This paper investigates the problem of static output feedback H∞ control for discrete-time Markov jump systems (MJSs) with partly unknown transition probabilities. Two design methods are presented to deal with it respectively. First, similar to the existing method of dealing with the unknown part of transition probabilities and with the help of the Finsler's Lemma, two sets of slack variables with...
By the insertion of a limited communication network in the feedback control loop, this paper investigates the quantized H∞ control problem for discrete-time systems with random packet losses. An improved quantized random packet-loss model is proposed and exploited to study the relationship among the packet-loss rate, the upper bound of consecutive packet losses, the quantization and the system performance...
The non-fragile dynamic output feedback Hinfin controller design problem affected by finite word length (FWL) for linear discrete-time systems is investigated. The controller to be designed is assumed to be with additive gain variations, which reflect the FWL effects in controller implementation. A notion of structured vertex separator is proposed to approach this problem, and exploited to develop...
This paper studies a quantized dynamic output feedback H∞ control problem for continuous-time linear time-invariant (LTI) systems. The quantizers considered here are dynamic and time-varying. For the quantized closed-loop system, a control strategy dependent on not only the controller states but also the system measurement outputs is proposed with updating two independent quantizer's parameters, such...
