Fault Tolerant Control of Internal Combustion Engine subject to Intake Manifold Leakage*

In this paper, a new FTC strategy of the diesel engine air path subject to intake manifold leakage described by Takagi-Sugeno model is presented. The proposed FTC design scheme integrates the state estimation, the leakage identification and the state feedback control law, to guaranty the stabilization of the faulty plant. State vector and leakage are estimated by an adaptive observer. The gains of the adaptive observer and feedback control law are obtained by solving a linear matrix inequality derived from the Lyapunov theory. The effectiveness and performances of the proposed approach are illustrated using the professional advanced diesel engine simulator AMEsim(LMS) platform in co-simulation with SIMULINK software.
