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...
This paper is concerned with the problem of robust Hinfin filtering for discrete-time switched linear systems with polytopic uncertainties in finite frequency domain. Based on generalized Kalman-Yakubovich-Popov (GKYP) lemma and switched Lyapunov functions, a switched full-order filter is designed such that the corresponding filtering error system is asymptotically stable and satisfies a prescribed...
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 presents a study on the problem of non-fragile state feedback Hinfin controller design for linear discrete-time systems with quantized signals. The quantizers considered here are dynamic and time-varying. With the consideration of controller gain variations and quantized signals at the same time, a new non-fragile Hinfin control strategy is proposed with updating quantizerpsilas parameters,...
