This paper studies the quantized H∞ filtering problem for continuous-time systems with a type of dynamic quantizers, which are conjuncted with static quantizers via dynamic scalings. The static quantizer ranges are fully considered here for practical transmission channels requirements. A quantized H∞ filter design strategy is proposed, where a convex optimization method is developed to minimize static...
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...
This paper presents a study on the problem of non-fragile H∞ controller design with sparse structure for SISO linear continuous-time systems. The controller to be designed with sparse structure is assumed to have additive gain variations, which are due to the finite world length(FWL) effects when the controller is implemented. Design methods for non-fragile H∞ controller with sparse structure are...
This paper studies the problem of non-fragile H∞ filter design for linear continuous-time systems. The filter to be designed is assumed to be with additive gain variations, which are due to the finite word length (FWL) effects when the filter is implemented. A notion of structured vertex separator is proposed to approach the problem, and exploited to develop sufficient conditions for the non-fragile...
