摘要
针对常规船舶模糊控制存在的缺陷,提出一种基于线性插值的船舶模糊控制方法,该方法可以在线计算出系统的控制输出,通过使控制规则表内相邻分档之间补充了无穷多个经过细分的控制规则,克服由于量化误差而引起的稳态误差和稳态颤振现象。以本校远洋实习船“育龙轮”为例,利用Matlab的Simulink工具进行了仿真研究,对比常规模糊控制,此种方法具有良好的控制性能。
A new method for constructing a fuzzy ship autopilot based on linear literpolation is presented. The method of mathematics is used to make the output of fuzzy controller changeable continuously. It can improve control precision and overcome steady - state flutter. Simulation using Matlab software for a far going experimental named ＂YULONG＂ shows high effectiveness in comparison with the ordinary fuzzy ship autopilot.
