Abstract

This paper investigates the passive fault-tolerant tracking control problem for a class of uncertain nonlinear system with intermittent fault and time delay. The considered intermittent fault appears in the actuator. The passive fault-tolerant tracking control scheme with a fuzzy logic technique is developed. Then, according to the information from residue fuzzy control will take the appropriate control action to minimizing the effect of the fault and track the reference. The effectiveness of the proposed passive fault-tolerant method is validated by a hybrid two-tank non-interacting level control system (HTTNILCS). The different error indices like integral Absolute Error (IAE), Integral Square Error (ISE) and Integral of Time-weighted Absolute Error (ITAE) is used to show the effectiveness of the proposed approach.
