Abstract

Electric governors are widely used in diesel engine applications. And a Proportional, Integral and Derivative(PID) controllers runs the electric governor in order to control the engine speed. However, it is difficult to analyze the system stability due to the non-linear characteristics of the diesel engine, and as a result, the PID controller should be tuned by trial-and-error approach. In this paper, a locally linearized diesel engine model is proposed based on the experimentally obtained engine torque map, and the proposed model is verified by simulations and experiments. Through the simulations and experiments it is concluded that the proposed model can be used in the system analysis and so to determine the PID controller gains.
