Sliding mode control for Turbocharged Diesel Engine

Fault-tolerant control based Super-Twisting algorithm for the diesel engine air path subject to loss-of-effectiveness and additive actuator faults

“…In this work the author suggested that for an optimal control performance, compressor mass flow W c and Exhaust pressure manifold P 2 are suitable choice for key output variable to be controlled. By a suitable change of coordinates, the authors in [6] proposed to replace the compressor mass flow set-point (W cd ) into an intake manifold pressure set-point (P 1d ). This transformation simplifies the control structure by defining new vector set-point(P 1d , P 2d ).…”

“…In this section, we report numerical results obtained from the simulation of controller (23) on the reduced third order model developed in (1)(2)(3)(4)(5)(6). Numerical simulations were performed in real-time Software In the Loop (SIL) using the dSpace modular simulator.…”

“…Indeed, in this work the authors developed a seventhorder model which describes the dynamics of the burnt gas fraction, the pressures, and the temperatures in the intake and the exhaust manifolds. For the purpose of developing a simplified model for control law design, and based on the assumptions that the dynamics of the fraction of the burnt gas and the temperatures are negligible, the seventh-order model is reduced to a third-order one (see the work in ( [5], [6])…”
