Abstract: The selection of best optimal control technique for air path of diesel engines is a challenging task in the present scenario. Control inputs of air dynamics such as Exhaust Gas Recirculation (EGR), Variable Geometry Turbine (VGT) & Fuelling have different properties with respect to their different applications. Hence, in this paper different optimal LQR control techniques are proposed for all three control inputs of air dynamics in diesel engine. The proposed controllers have been implemented using MATLAB/SIMULINK@ platform and the results are compared with the individual, coordinated & switching control inputs.
Keywords: LQR, Optimal Control, Switched Linear Systems, EGR & VGT.
Scope of the Article: Control and Automation
