Abstract

Fault diagnosis and accommodation(FDA) for nonlinear multi-variables system under multi-fault are investigated in the paper. A complete FDA architecture is proposed by incorporating the intelligent fault tolerant control strategy with a cost-effective fault detection and diagnosis (FDD) scheme based on a multiple-model. The schem efficiently handles the accommodation of both the anticipated and unanticipated failures in online situations. The three-tank with multiple sensor fault concurrence is simulated, the simulating result shows that the fault detection and tolerant control strategy has stronger robustness and tolerant fault ability.
