Passive Fault-Tolerant Control for the Diesel Engine Air Path Subject to Loss-of-Effectiveness and Additive Time Varying Actuator Faults

Abstract

In this paper we developed a passive fault tolerant control strategy for the diesel engine air path. This strategy is carried out under the concept of Higher Order Sliding Mode Control (HOSMC). The proposed fault tolerant strategy incorporates a super twisting controller which handles parametric uncertainties and actuator failures. In this paper we consider two types of actuator failures, additive and loss-of-effectiveness faults. The simulations of the proposed controller on a recently validated experimental air path diesel engine model, show good results for actuator failures conditions even in the presence of uncertainties on model parameters.
