Passivity based control of a turbocharger-diesel engine system with exhaust gas recirculation

摘要

A new nonlinear passivity based controller for a diesel internal combustion engine with variable geometry turbocharger system is presented. The controller design uses three input-output pairs. An input-output pair is used to stabilize the zero dynamics of the system and for the other two pairs controllers are designed such that a two-inputs two-outputs passive systems that allows output tracking is obtained. The proposed controller is applied to the nonlinear multivariate model diesel engine and its performance is verified through simulations.
