摘　　要：Ｋｏｓｋｏ倒车系统有许多不能到达停车位的死区和准死区．为此，作者设计了一个模糊预测器，在不改变控制系统规则的前提下，给出卡车到达停车位的中间目标，以改变它原来的倒车轨迹，使得卡车从准死区也能到达．所采用的模糊规则比重新设计大大减少．仿真结果表明，一个简单的模糊预测器能实现复杂的行为．从而提供了一种设计复杂控制系统的新思路．Kosko designed a truck backer upper fuzzy control system which works robustly. But at some position it cannot work well. In order to improve the system, a new design is necessary. If a single fuzzy system is applied, the design is complex. In this paper, a double fuzzy system is presented for this purpose, in which a fuzzy 'park' position predictor is utilized. A simple fuzzy predictor can do a good job. With the fuzzy predictor, some simulations are given in this paper. Combining Koskos truck backer upper control system with the predictor, the truck is operated very well, just as by a chauffeur. From this example a conclusion is given: a simple fuzzy predictor can advance your control system greatly.
