Abstract This article investigates the fault estimation and tolerant control (FTC) problems for linear stochastic uncertain systems. By introducing fictitious noise, is augmented as part of systems state, then a robust estimator proposed to simultaneously obtain state estimation. Based on estimated information, active FTC presented eliminate impact fault. Finally, simulation example conducted d...
This paper is concerned with the stochastic finite-time stability and stochastic finite-time boundedness problems for one family of fuzzy discrete-time systems over networks with packet dropout, parametric uncertainties, and time-varying norm-bounded disturbance. Firstly, we present the dynamic model description studied, in which the discrete-time fuzzy T-S systems with packet loss can be descr...
We study the problem of fault diagnosis, i.e., localization of difference(s) between an implementation and a specification in systems modelled by finite state machines. We show that even considering only a single fault in a finite state machine there are some situations when the exact diagnosis of the fault cannot be assured. We give an algorithm for fault diagnosis. If it is possible the proce...
Disk Type Variable Reluctance (DTVR) resolvers have distinguished performance under run out fault comparing to conventional sinusoidal rotor resolvers. However, their accuracy under inclined rotor fault along with different types of eccentricities includes static and dynamic eccentricities are questioned. Furthermore, due to thin copper wires that are used for signal and excitation coils of res...
The theory behind fault tolerant multi-level Monte Carlo (FT-MLMC) methods was recently developed and tested. These tests were made without a real fault tolerant implementation. We implemented an MPI-parallelized fault tolerant MLMC version of an existing parallel MLMC code (ALSVID-UQ). It is based on the User Level Failure Mitigation, a fault tolerant extension of MPI. We confirm our FT-MLMC t...
With the increasing demand for higher performance, safety and reliability of dynamic systems, fault diagnosis has received more and more attention. The observer-based strategy is one of the active research fields, which is widely used to construct model-based fault detection systems for technical processes which can be well modelled as linear time invariant systems. Fault diagnosis for nonlinea...
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...
