基于模糊控制的船舶发电机自动化测试系统

盐水缸是船舶电站试验中常用的负荷设备,采用了基于组态王和PLC的模糊控制器实现盐水缸功率的自动控制,可以在线实现PID参数自整定,使液位控制系统的相应速度加快,超调量减少,过渡时间缩短,具有较强的鲁棒性和稳定性;该测试系统改善了传统船用发电机的测试手段,实现了发电机试验负荷的自动调节和发电机试验数据的自动记录,节约了大量的人力物力,使得船舶电站的调试周期由原来的7天缩短为3天,其中仅燃油一项每条船就节约近3万元。

Marine Generator Automation Test System Based on Fuzzy Control

Salt water vats are commonly used in ship power plant experiment as load test.This paper presents a fuzzy controller based on KingView and PLC,which can achieve automatic control of power salt water tanks and online self-tuning PID parameters,accelerate the corresponding speed of Liquid level control system,reduce the overshoot,shorten the transition period,has strong robustness and stability.This test system improved the test method of the traditional marine generator.It has realized automatic control of t...
