Diesel engine variable-geometry turbine turbocharger controlled by a multi-agent-based algorithm

Abstract

This paper provides an innovative technique for the control of a variable-geometry turbine in a turbocharged compression ignition engine. Such a control algorithm is based on a multi-agent System scheme. It is seldom that agents are considered as stand-alone systems; on the contrary, their main strength can be found in the interaction with other agents, constituting the so-called multi-agent System. An agent is a software or hardware entity that can receive signals from the environment and act upon that environment through output signals, trying to carry out an appropriate task. In the present paper, a fuzzy logic system has been employed for the agents' internal structure. In order to test the performance of the proposed control technique, a numerical model of the engine has been used, which employs a thermodynamic (zero-dimensional) approach. The paper will show that the proposed control technique is able to take into account the non-linearity of the controlled system.
