摘要
减摇水舱是一种减小船舶横摇的重要装置,建立船舶试验台是对其进行研究的主要手段.文章针对两自由度船舶试验台横摇位置系统建模中忽略的参数不确定及非线性环节等因素,设计了一种基于模糊逻辑的PID控制器.该控制器能够实现PID控制参数的实时调节,实验研究表明其在实际系统中具有优于常规PID控制器的性能.
The anti-rolling tank is an important device to reduce the rolling of ship. Building a ship testing platform is a main measure to study anti-rolling tank. In this paper, aiming at the time change parameters and nonlinear factors neglected in the modeling of the rolling position servo system of two freedom degree ship testing platform, a type of PID controller based on fuzzy logic is designed. It can regulate the parameters of PID controller in real time. The research experiments show that this controller has better performance than normal PID controller in actual system.
