We consider the problem of detecting malfunctions in the actuators or sensors of systems which can be described by nonlinear/non-Gaussian stochastic state-space models. The basic idea is to estimate the state vector of such models using a sequential Monte Carlo technique known as particle filtering. We present several approaches to detecting faults and pinpointing their location within the system,...
This paper presents one way to adaptation of Doppler radar filters. Doppler filters use window function in order to estimate the target velocity. The window function length can be adapted depending on estimated target acceleration and estimated signal to noise ratio in the system. Kalman filter is used for estimation of target acceleration. Signal to noise ratio is estimated using a procedure based...
A two layer fault detection and isolation (FDI) system for coal-shortage detection in thermal power plant coal supply unit has been proposed. If the amount of coal reaching the burners is not sufficient enough we are facing possibly hazardous working conditions and this situation is treated as fault and has to be detected as soon as possible. Layer one of a proposed system consists of two FDI algorithms...
