The marine diesel engine speed automatic controller has an important mission in the field of keeping the setting speed constantly in the variable sea environment. Before, the conventional PID (Proportional – Integral – Derivative) controller is being used popularly at present for marine diesel engine speed automatic control. However, this is a traditional controller having some disadvantages such as the variable characteristics and realizable degree are still low. In this article, a research on modern control theory has been referred as an effective solution to restrict the drawback of conventional PID controller. Fuzzy logic control theory has been studied in this research. The theoretical methodology of fuzzy control theory has been identified. A case of study has been adopted by applying to fuzzy logic control in order to control marine main diesel engine speed when considering the navigation environment of the ship. So as to gain an effective diesel engine speed control process then experimental knowledge plays a vital role in control process. The authors have based on operational experience on some ships associating with the experimental investigation from Chief Engineers to design fuzzy logic main diesel engine speed controller. The modern diesel engine speed controller is more stabler than the conventional controller. The main object of this research is diesel engine speed through simulating the diesel engine speed controller on SIMULINK/MATLAB environment. The validation process of this control model has conducted on a certain bulk carrier of VINIC shipping transportation company in Vietnam. The rotational speed controller and diesel engine are numberred and simulated on SIMULINK environment. The results of this study indicate that proposal controller is meaningful in the field of establishment of diesel engine speed controller. Furthermore, the design of optimal diesel engine speed controller is useful to save the fuel oil consumption of marine diesel engine and decrease the harmful exhaust gases emission nowadays. The study result will be brought the main diesel engine fuzzy controller realiably and a basis of next research.
