In this paper, we consider the H∞-filtering problem for affine nonlinear singular (or descriptor systems). Two types of filters are discussed, namely, 1) singular and 2) normal, and sufficient conditions for the solvability of the problem in terms

In this paper, we consider the H2 (or Kalman)-filtering problem for discrete-time singularly-perturbed (two time-scale) nonlinear systems. Two types of filters, namely, i) decomposition and ii) aggregate, are discussed, and sufficient conditions for

This paper investigates the problem of global strong stabilization by state feedback, for a family of high order feedforward nonlinear time-delay systems. The uncertain nonlinearities are assumed to satisfy a polynomial growth assumption with an inpu

In this article, we introduce, formulate and solve the W1,2, W1,∞ nonlinear optimal control problems as extensions of H2, H∞ optimal control problems, respectively. As these spaces contain less smooth functions, a larger number of problems could

In this article, we introduce, formulate and solve the W1,2 and W1,∞ estimation problems. We propose proportional, proportional-derivative and proportional-integral (PI) filters for each problem, and we derive sufficient conditions for the existenc

In this technical note, constructive control techniques have been proposed for controlling feedforward nonlinear time-delay systems. The nonlinear terms admit an incremental rate depending on the input or delayed input. Based on the Lyapunov-Razumikh

This paper concerns H∞ control problem for a class of discrete-time uncertain switched linear systems with average dwell time. The stability result for general discrete-time switched systems is first explored, and a µ-dependent approach is then in

In this article, the fault detection (FD) problem for a class of discrete-time Markov jump linear system (MJLS) with partially known transition probabilities is investigated. The proposed systems are more general, which relax the traditional assumpti
