FAULT-TOLERANT FITTING AND ONLINE DIAGNOSIS OF FAULTS IN SISO PROCESS

摘要

In this paper, a series of recursive fault-tolerant (FT) fitting algorithms are built for therntrajectories of a SISO process when some pulse-type faults arise from output components of thernprocess. Based on the recursive FT fitting, a series of practical program are given to online detectrnpulse-type faults in process and to identify magnitudes of these faults. Simulation results show thatrnthese new methods are efficient.
