Abstract:
Fault detection is essential in precision mechatronics to facilitate maintenance and minimize operational downtime. The aim of this paper is to develop a systematic procedure from identification to accurate nullspace-based fault diagnosis, accounting for the influence of noise and interaction in multivariable closed-loop control configurations. The influence of noise and interaction on the model estimate and fault diagnosis system are investigated through the use of closed-loop operators and by means of an illustrative case study.
