Abstract
The marine main diesel engine rotational speed automatic control plays a significant role in determining the optimal main diesel engine speed under impacting on navigation environment conditions. In this article, the application of fuzzy logic control theory for main diesel engine speed control has been associated with Particle Swarm Optimization (PSO). Firstly, the controller is designed according to fuzzy logic control theory. Secondly, the fuzzy logic controller will be optimized by Particle Swarm Optimization (PSO) in order to obtain the optimal adjustment of the membership functions only. Finally, the fuzzy logic controller has been completely innovated by Particle Swarm Optimization algorithm. The study results will be represented under digital simulation form, as well as comparison between traditional fuzzy logic controller with fuzzy logic control–particle swarm optimization speed controller being obtained.
Highlights
Fuzzy logic control was proposed by Prof
The fuzzy logic controller for main diesel engine speed has been brought a lot of advantages instead of using traditional PID (Proportional–Integrative–Derivative) controller
This study has associated with particle swarm optimization (PSO) algorithms along with fuzzy logic controller for main diesel engine on ships that achieved benefits
Summary
Fuzzy logic control was proposed by Prof. Zadeh in 1965. The mathematical model does not need to establish in design process of a fuzzy logic controller. Particle Swarm Optimization (PSO) algorithm has been used to get the optimal values from fuzzy logic control rules. The combination between fuzzy logic control and PSO has been conducted by some researches at individual field. V, et al have introduced evolutionary methodology for combining Particle Swarm Optimization (PSO) and Genetic Algorithms (GAs) when using fuzzy logic control for decision making [13]. Particle Swarm Optimization algorithm is studied to choose the membership functions and the fuzzy control rules. The combination between fuzzy logic control and PSO will help the control process more realizably when considering the control objective is diesel engine speed.
