摘　　要：为解决路面发生跃变时车轮抱死的问题,提出一种分解式PID模糊控制器(P-I-D Fuzzy),并应用于ABS。建立模糊系统输出与输入的函数关系,结合PID表达式,理论分析表明该型控制器具有类似参数自适应整定PID的功能。分别在典型的高、中、低附着路面,以及跃变路面上进行仿真实验。结果表明这种控制器适应性强,在跃变路面下,超调量小,跟踪迅速。In order to resolve the problem of wheel lock when road surface changes suddenly, a decomposed PID fuzzy controller, P-I-D Fuzzy, is proposed and used by ABS. The mathematical relation between input and output of fuzzy system is established, combined with PID expres- sion. The theoretical analysis shows that the controller has similar function with self-adapting PID. Simulation is done for high, medium, low adhesion road surface and changing adhesion road surface. The results indicate that the controllerg adaptability is more excellent;and when road conditions change it provides less overshoot and shorter setting time.
