Abstract

This paper describes a wireless based networked control system (NCS) and its diagnosis. The purpose is to show the specific characteristics of a wireless network compared to a classical wired network and their consequences on the diagnosis. A comparison of residuals generated to detect and isolate sensor faults in a control loop is made when two network protocols are used: a CAN network and a ZigBee wireless network. An additional residual is proposed to differentiate sensor faults from packet losses. A reconfiguration procedure is used to improve control performance in case of packet losses. A D.C motor control and diagnosis are simulated with Matlab/Simulink while the networks are simulated with TrueTime 1.5. A distributed diagnosis strategy is also proposed from overall system perspective.
