Model Predictive Control Of Diesel Engine Air Path With Actuator Delays

Existing results show that Model Predictive Control (MPC) can satify the desired settling time, zero steady-state error, and overshoot criteria for the MIMO control of the Diesel Engine Air Path (DEAP) system. However, the effect of actuator delay that considerably affects system performance, is not addressed sufficiently. In this study, MPC of DEAP is extended with a delay term added to the actuators Exhaust Gas Recirculation valve and Variable Geometry Turbocharger valve on the plant model. A linear state-space model of the plant is obtained by using system identification techniques and the states of the identified model are extended due to delay term. It is shown that MPC performs better when the delay is taken into account in the algorithm. Copyright (C) 2019. The Authors. Published by Elsevier Ltd. All rights reserved.
