Fault Detection Filter for Linear Time-Delay Systems

چکیده
By extension of a fault detection optimization approach to linear time invariant (LTI) systems, this short paper deals with the fault detection filter (FDF) problem for linear time-delay systems with L2-norm bounded unknown inputs. The basic idea is first to introduce a new FDF as the residual generator; and then based on an objective function to formulate the FDF design as an optimization problem. Through appropriate choice of the filter gain matrix and a post-filter, the convergence of the residual generator and satisfactory FDF performance can be achieved. A numerical example is given to illustrate the effectiveness of the proposed method.

Fault Detection for State-delay Fuzzy Systems Subject to Random Communication Delay
This paper is concerned with the problem of fault detection for discrete-time state-delay fuzzy systems. It is assumed that the output measurements are subject to random communication delay. The random communication delay is modeled as a finite state Markov process, and it is assumed that the transition probabilities are partially known. The problem addressed is the design of a delay-mode-depen...
متن کاملDelay-dependent fault detection for switched linear systems with time-varying delays - the average dwell time approach
In this paper, the fault detection problem is investigated for a class of discrete-time switched linear systems with time-varying delays. The main purpose is to design a fault detection filter such that, for all unknown inputs, control inputs and time delays, the estimation error between the residual and fault is minimized in an exponential way. The fault detection problem is converted into an ...
متن کاملH∞-based fault detection for nonlinear networked systems with random packet dropout and probabilistic interval delay
The fault detection problem for the nonlinear networked control system (NCS) with packet dropout and delay is investigated. A nonlinear stochastic system model is proposed to account for the NCS with random packet dropout and networkinduced non-uniformly distributed time-varying delay in both from sensor to controller (S/C) and from controller to actuator (C/A). Based on the obtained NCS model,...
متن کاملFault detection of networked control systems in stochastic environments
This paper deals with the problem of fault detection for networked control systems in the stochastic environments. The packet dropout, networkinduced delay and out-of-order packets due to long delay are assumed to exist stochastically in the sensor-to-controller link and the controller-toactuator link. By assuming that the stochastic environment could be described as a homogeneous Markovian cha...
متن کاملFault Detection Filter for Nonlinear Systems Using Linear Approximations
In this paper, the design of a fault detection filter for nonlinear systems is presented. The nonlinear system is represented as a sequence of linear timevarying approximations and at each linear approximation the design of an optimal stochastic fault detection filter for linear time-varying systems is applied. The final residual is primarily affected by a target fault and minimally by nuisance...
