A simplified version of the dedicated observer scheme for detecting incipient instrument failures in automatic systems is presented. This scheme requires only a single observer, driven by a single instrument. Simple logical combinations of estimated instrument outputs from the observer with the actual instrument output allow small faults in all the instruments to be detected. Tests on a simulation of a practical system indicate the scheme is robust with respect to a small uncertainty in a dynamic parameter of the controlled plant.
