A fault and delay tolerant multi-sensor control scheme
Abstract
The present article deals with a fault and delay tolerant multi-sensor control scheme. In particular, we consider a process aected by additive disturbance which is monitored by redundant sensors. The process is controlled by a digital controller which is connected with the sensors via shared network. It is assumed that sensors are subject to abrupt faults while the communication between the sensors and the controller is aected by time-varying delay. In order to tackle network-induced delay, we design a prediction-based controller with compensation. A fault and delay detection and identication mechanism is designed as well.
