摘要:

在采用最大相对速度-距离法的基础上,引入模糊逻辑控制时间裕度,使任意两次检测间的时间间隔适当增大。该方法不仅减少了检测次数,更主要的是利用模糊逻辑的鲁棒性,减少了误差对检测结果的影响,从而使它无论在效率还是在可靠性方面都有了提高。以运动平面多边形为例,通过不采用、采用、部分采用模糊逻辑控制3种方法加以比较,表明了该方法的可靠性和有效性。

Abstract:

The theory of maximum relative velocity distance is provided, and the fuzzy logic is used to control the time margin. The algorithm makes the time interval between two detections enlarged properly. Because the fuzzy logic has robustness, the algorithm not only reduces the times of detection, but also makes the effect of error less. So, it enhances both efficiency and reliability remarkably. An example of moving polygons is presented. Three methods, that is not using, using, and half using fuzzy logic control, are used to deal with it. The analysis of the results shows that the proposed method is effective.

Key words: time mar gin, fuzzy logic contr ol, interfer ence detection
