The control algorithms for the electronic governor of the Diesel engine fuel injection system were developed by using the simplified effective dynamic models. The electronic governor assembly was modeled as the second order with time delay, and parameters in the model were obtained by using experimental data. The engine assembly was modeled as the second order with time delay. These models were effectively used for the development of the idle and the rpm-deviation control algorithm for the fuel injection rate control system.<br/>
The idle control algorithm was developed for the engine idle speed control, and the rpm-deviation control algorithm was developed for the control of each piston's rpm-deviation from the average rpm speed. The multi-structured control algorithm with the bumpless feature was used for the idle control algorithm, and the feedforward control algorithm was used for the rpm-deviation control algorithm. These control algorithms result in the effective control of the fuel injection rate<br/>
