The problem of L1-induced performance analysis for continuous positive systems with time-delay is investigated in this paper. At first, we propose a integral method to compute the value of the system L1-induced norm, and the relationship between the transfer function and L1-induced norm of such systems is obtained. Then, the necessary and sufficient condition is given to ensure that such systems are...
In this paper we investigate the cooperative output regulation problem of linear multi-agent systems with a switched exosystem which is assumed that some subsystems are Hurwitz stable, some are neutral stability, and the others are unstable. We will deal with two difficulties in the paper. One is the complexity of the switched exosystem trajectory. The other is the limited information exchanges of...
This paper investigates the stability for a class of switched nonlinear systems. Firstly, an improved average dwell time (ADT) method is introduced, based on which an improved mode-dependent dwell time (MDDT) method is established. Then, several new results to the stability analysis are obtained. In comparison with the existing results, the obtained results have some advantages over those obtained...
This paper investigates the input/output-to-state stable in the mean (IOSSiM) property of switched stochastic nonlinear (SSN) systems. First, we present a new IOSSiM result for the SSN systems whose subsystems are IOSSiM by applying an improved ADT method. Second, by extending the improved ADT method to unforced nominal SSN systems in which parts of subsystems are stable, we establish a new stability...
In this paper, the problem of finite-time H∞ fuzzy control for both continuous-time and discrete-time nonlinear systems is considered. The definitions and explanations about finite-time H∞ fuzzy control for both continuous-time and discrete-time nonlinear systems are offered. Some theorems are obtained to guarantee the provided performance requirements. The optimization algorithms are also designed...
By exploring some geometric properties of the logarithmic quantizer and using the fact that the logarithmic quantizer is sector bounded and nondecreasing, this paper presents a new approach to the stability analysis of quantized feedback control systems. Our method is based on Tsypkin-type Lyapunov functions that have been widely used in absolute stability analysis problems. The results are expressed...
With the wide use of computer and the rapid development of network technology, the research in the emerging area of networked control systems (NCSs) has attracted considerable attention in the research community. The purpose of this survey is to provide a review of state-of-the-art of such research. We particularly discuss things as follows: event-driven sampling for energy and communication efficiency,...
