ABS模糊自适应控制器的设计与仿真研究

基于最佳滑移率的ABS自适应控制器要解决的问题有：在制动过程中,滑移率被稳定的控制在目标滑移率附近;自动识别道路附着状况,调整目标滑移率值以达到利用最大道路附着系数的自适应效果.本文在建立车辆单轮防抱死仿真系统的基础上,使用模糊控制,设计了一个基于最佳滑移率的复合式模糊自适应控制器。经ABS系统仿真实验表明,该控制器的控制稳定性、鲁棒性和自适应性均取得了良好的效果。

Design and Simulation of ABS Fuzzy Serf-adaptive Controller

The problems are supposed to be solved in the basing on slip rate of the serf-adaptive ABS controller are as follows:in the braking process,the slip rate control is been stable around the target slip ratio;it can identify the road characteristic automatically to get the best bra-king effect. This paper on the establishment of a single wheel of vehicle ABS system.using the way of fuzzy control,designed a based on best sliding rate compound fuzzy serf-adaptive controller. Run the fuzzy controller and then the whole system. The system simulation experiment re-sults show that their control stability, robust and adaptability are effective.
