非线性PID技术在船舶调距桨控制的应用

Application of nonlinear PID technology in the pitch controlled propeller of ship

推进系统是船舶的动力来源,近年来,我国船舶工业发展迅速,对船舶推进技术的要求越来越高。可调螺距螺旋桨可以根据船舶的实际工况(速度、载荷等)调节螺距角,从而提高螺旋桨的推进效率和机动性,提高船舶的航运能力,是一种应用较为广泛的螺旋桨。本文针对船舶可调螺距螺旋桨的自动化控制问题,系统介绍了非线性PID控制技术,在此基础上研究了基于PID的船舶调距桨控制系统,并对该系统进行了仿真研究。

Propulsion system is the power source of ship.In recent years,the shipbuilding industry of our country has developed rapidly,and the requirement of ship propulsion technology is higher and higher.Adjustable pitch propeller can according to the actual conditions of the ship(speed and load) adjust the pitch angle,so as to improve the propulsion efficiency of the propeller and ship maneuverability,improve shipping capacity,is a widely used propeller.Aiming at the problem of automatic control of ship controllable pitch propeller,introduces the system of nonlinear PID control technology,on the basis of the research on the marine controllable pitch propeller control system based on PID,and the system simulation.
