船舶航速智能控制系统仿真

利用MATLAB建立了船舶推进系统的数学模型,采用传统的PID算法,并利用遗传算法整定PID参数,对某船航速控制系统进行了仿真分析.为反映真实情况,文章分别仿真了船舶在无干扰、5%、10%及20%干扰情况下航速及螺旋桨转速等参数的变化,仿真结果显示遗传算法整定PID参数用在船舶航速控制系统上是可行的.

Simulation of marine intelligent speed control system

After building the mathematical model of marine impellent system by means of MATLAB,this paper adopted traditional PID algorithm and used the genetic algorithm to regulate the parameters of PID controller for making simulation and analyses on the speed control system of certain ship.To reflect the true condition,at the same time,it made respective simulation on the change of such parameters as navigational speed and rotate speed pf the screw propeller,etc.under such conditions as no disturbance,5%,10% and 20% disturbance.Simulation results showed that it is feasible to apply the method of regulating PID parameters by means of genetic algorithm in marine navigational speed control system.
