[ 1 ] - Designing of LQIG method for controlling the wastegate of a turbocharged diesel engine to increase engine output power using experimental results of engine test chamber laboratory

In this paper, first, using a test set on a turbocharged diesel engine in the engine test room, a nonlinear model is obtained and it is linearized around several operation points. Then, for the linear models, a linear quadratic integral Gaussian controller (LQIG) with variable parameters as function of engine speed is designed and simulated. In the proposed method, by controlling the wastegate,...
