We address the problem of making nonholonomic vehicles, with second-order dynamics and interconnected over a bidirectional network, converge to formation centered at nonprespecified point on plane common orientation. assume that only Cartesian position center mass each vehicle its orientation are available for measurement, but not velocities. In addition, we interconnections affected by time-va...

This paper is concerned with the problem of asymptotic stability for linear systems with time-varying delays. With the introduction of delay-partition approach, some new delaydependent stability criteria are established and formulated in the form of linear matrix inequalities. Both constant time delays and time-varying delays have been taken into account. Numerical examples are given to demonst...

a memory control for t-s fuzzy discrete-time systems with sto- chastic input delay is proposed in this paper. dierent from the common assumptions on the time delay in the existing literatures, it is assumed in this paper that the delays vary randomly and satisfy some probabilistic dis- tribution. a new state space model of the discrete-time t-s fuzzy system is derived by introducing some stocha...

We adopt the optimization framework for the rate allocation problem proposed by Kelly and investigate the stability of the system with arbitrary communication delays between network elements with time-varying queue dynamics. We first present the conditions for the existence of a solution of the system. Second, we establish the conditions for the system stability with arbitrary delays for a fami...

Networked control systems (NCS) have recently received an increasing attention from the control systems community. One of the major problems in NCS is how to model the highly nonlinear terms caused by uncertain delays such as time-varying input delays. A straightforward solution is to employ polytopic approximations. In this paper we develop a novel method for creating discrete-time models for ...

This paper has proposed a controller design method for networked control systems with network induced delays by using LMI-based delay-dependent optimization. The delays are described by a Markov chain, since they are to be time-varying and even longer than the sampling time. A delay-dependent compensation method has been proposed here with a jump linear system analysis technique to stabilize th...
