Marine Sink-Float Safety Device’s Control System Based on Fuzzy Control

Zi Yue Wu, Jie Qi, Chen Nan Xue


In order to ensure safety work of marine equipment, this paper introduces a kind of sink-float safety device which can match with marine equipment to realize protection work, and a fuzzy controller set up by fuzzy control algorithm. The data of the control system is collected by multi-sensor and filtered through the filter circuit. Under a 5 grade sea condition, the marine sink-float safety device can carry marine equipment, escaping from the harsh marine environment by diving to a certain depth. The simulation in MATLAB/Simulink shows that the control system could response fast and operate stably. Furthermore, it is able to control sink-float safety device efficiently and reach to the preset depth accurately. So we can guarantee the operation of marine equipment reasonably.
