基于遗传算法的模糊控制型船舶自动驾驶仪研究

摘要

Several defects of general Autopilot of ship are reviewed in this paper. In view of the nonlinearity of ship steering with time varying parameters, the paper puts forward a control system which consists of Bang-Bang controller and fuzzy controller based on the genetic algorithm. The method improves the precision of the control system. The fuzzy autopilot of ship based on the genetic algorithm is compared with the general fuzzy autopilot of ship through numerical simulation. It is shown that the presenting method has good control performance.%该文分析了常规船舶自动驾驶仪存在的缺陷,针对船舶操作这种非线性、时变参数的控制对象,提出了一种基于遗传算法的模糊控制型和Bang-Bang控制相结合的控制系统,提高了模糊控制系统的精度:最后,通过仿真将模糊型船舶自动驾驶仪与基于遗传算法的模糊控制型船舶自动驾驶仪的性能作了比较,结果表明该文所提出的方法控制性能良好.
