ABSTRACT
The degree of speed control of ship machinery effects on the economics and optimization of the machinery configuration and operation. All marine vessel ranging need some sort of speed control system to control and govern the speed of the marine diesel engines. Impractical and dangerous to have a ship or boat without speedcontrol mechanism fitted on it, and could lead to accidents such as collision or grounding. Traditionally, engine speed regulation is achieved using classical gain-scheduled PID control to address the variable operating conditions of the engine. In this paper we present a mathematical model to describe the rotation speed regulationprocess of a marine diesel engine and the parameters of PID controller are optimized by Genetic Algorithms (GA). The result of simulation shows that the Genetic Algorithms (GA) is able to improve operational reliability and efficiency of marine diesel engine.
