We consider Networked Control Systems (NCSs) consisting of a LTI plant; a linear static or dynamic feedback controller; a collection of sensors that provide measurements to the controller; and a collection of actuators that are used to control the plant. The different elements of the control system are spatially distributed, but interconnected through a communication network. Due to the shared ...

This paper investigates the reliable stabilization problem for a class of nonlinear networked control systems (NCSs) under variable sampling with variant state and network delays. An equivalent continuous-time uncertain fuzzy system with both state and input time varying delays, subject to possible actuator faults, is derived based on the Takagi-Sugeno (T-S) model and the input delay method. In...

We study long run average behavior of generalized semi-Markov processes with both fixed-delay events as well as variable-delay events. We show that allowing two fixed-delay events and one variable-delay event may cause an unstable behavior of a GSMP. In particular, we show that a frequency of a given state may not be defined for almost all runs (or more generally, an invariant measure may not e...

This paper focuses on the non-fragile guaranteed cost control problem for a class of T-S fuzzy time-varying delay systems with local bilinear models. The objective is to design a non-fragile guaranteed cost state feedback controller via the parallel distributed compensation (PDC) approach such that the closed-loop system is delay-dependent asymptotically stable and the closed-loop performance i...

Finite State Machine (FSM) is widely used in electronic systems and its reliability critical to the system. Ionizing radiation induced soft error one of major concerns design systems, especially avionics or space applications. Nowadays, majority relies on single-error correction, double-error detection (SEC-DED) codes mitigate errors. However, presence multiple bit upsets becoming more prevalen...

This paper investigates the problem of decentralized model reference adaptive control (MRAC) for a class of large scale systems with time varying delays in interconnected terms and state and input delays. The upper bounds of the interconnection terms are considered to be unknown. Time varying delays in the nonlinear interconnection terms are bounded and nonnegative continuous functions and thei...

In this paper we introduce some stability criteria for impulsive fuzzy system of differential equations with finite delay in states. Firstly, a new comparison principle for fuzzy differential system compared to crisp ordinary differential equation, based on a notion of upper quasi-monotone nondecreasing, in N dimentional state space is presented. Furthermore, in order to analyze the stability o...

The vision based moving target tracking is a key technology for unmanned systems in complex environments, which mainly limited by the visual measurement delay and kinematic uncertainties. In this paper, time-delay disturbance observer sampled-data control approach developed servoing of an inertially stabilized platform. As camera employed to capture position target, generated acquisition proces...
