Abstract

According to the designing method of robust sliding mode observers based on LMI in the references ^[8], the problems of the multiplicative fault detection and reconstruction in linear dynamic systems are studied. By designing robust sliding mode observers with LMI and applying the equivalence output error concept, the fault information is obtained so that multiplicative faults are detected and reconstructed. The numerical simulation results are presented to validate the approach.
