A COMPARISON OF THE STABILITY OF THE SHIP AUTOPILOT SYSTEM USING PSO-PID AND FUZZY ALGORITHMS

Abstract

The control objective of the ship control system is to control the heading and change of direction of the ship to follow up the desired heading under the effect of external factors acting on the ship. In this paper, we study the stability of a ship autopilot system based on the PSO-PID control algorithm and the Fuzzy control algorithm under the effects of environmental disturbances, including current, wind, wave, and high-frequency wave noise. Especially, the parameters of the factors affecting the ship were surveyed by the actual conditions of the Vietnam sea environment from Binh Thuan province to Ca Mau province, which can increase the reliability of the proposed algorithm. The performance of the algorithms was evaluated through simulation results using Matlab/Simulink software.
