In this paper, the stability problem of bilateral tele-operation systems with data sampling and communication time delays is considered. Two buffers are introduced in the bilateral teleoperation control framework to deal with the issue that the information transmitted between the master and slave sides suffer from time-varying delays. The mathematical model of bilateral teleoperation systems based...
This paper studies the stability and stabilization of switched Boolean networks (SBNs) with impulsive effects. The dynamics of SBNs with impulsive effects is converted to an algebraic form, based on which, some criteria are presented for the stability of SBNs with impulsive effects. These conditions include the arbitrary switching signal case and the state feedback switching signal case. In addition,...
This paper studies the static output-feedback control in a class of linear networked control systems and an improved adaptive event-triggered strategy is designed to save the limited network bandwidth. Different from the existent methods, the proposed event-triggered strategy can relax the assumption of the prior works that the threshold of event-triggered communication scheme is a preselected constant...
This paper addresses the robust non-fragile leader-following consensus problem for multi-agent systems against state-dependent uncertainties and controller coefficient variations. Without the requirement of knowledge of uncertainties of agents and controllers, adaptive distributed controllers are constructed to guarantee the follower agents tracking the leader agent. Asymptotic consensus results of...
Analog signal sampling is one of the most fundamental topics in engineering sciences. The classical Shannon theorem is proposed for the band-limited signals, and so far it has been a cornerstone in signal processing and communication theory. In this work, we present a group of local time domain theorems for sampling differentiable continuous analog signals through Lagrange interpolation, and show...
This paper investigates the semi-global practical stabilization for second-order nonlinear systems subject to unknown control coefficients and completely unknown nonlinear function. In order to achieve the control objective, a state feedback controller is firstly constructed to ensure that systems under consideration satisfy uniform Lyapunov property. Then, based on output feedback domination method,...
An approach is proposed to reasoning problems based on Petri nets (PNs). First, a method is presented modeling a world by describing Boolean variables as PN loops. Second, an algorithm is introduced to rearrange inference rules as conjunctive normal forms (CNFs), and, in turn, CNFs are transformed into linear constraints. Consequently, a knowledge base system (KBS) PN is obtained by designing monitor...
In this paper, the problem of H∞ sliding mode control for discrete-time singular systems with time-varying delay is studied. A new type of sliding mode surface involving the singular matrix E is proposed firstly, based on which, a less conservative condition is obtained to guarantee the ideal sliding mode dynamics of the singular system to be admissible with a γ-Ievel disturbance attenuation of the...
