摘　　要：本文基于对常规船舶自动驾驶仪存在缺陷的分析,提出了一种基于线性插值模糊控制和Bang-Bang控制相结合的控制系统,使模糊控制输出连续变化,提高了模糊控制系统的精度。通过常规模糊型船舶自动驾驶仪与改进后的模糊型船舶自动驾驶仪性能的比较,表明本文所提出的方法是行之有效的。After the several disadvantages of general ship autopilot are analyzed in detail, the control system which consists of Bang-Bang controller and fuzzy controller based on linear interpolation is put forward in this paper. The method of mathematics is used to make the output of fuzzy controller changeable continuously to improve the precision of the system. By comparing linear interpolation fuzzy autopilot of ship with general fuzzy autopilot of ship in performance, it is shown that the method presented by authors is effective.
