基于模糊控制的汽车ESP系统仿真

摘要

为提高汽车的操纵稳定性，基于多体动力学分析软件MSC．ADAMS／Car建立了汽车的整车动力学模型。根据汽车稳定性控制的基本原理，在Matlab／simulink环境下建立了ESP模糊控制系统并制定了相应的控制规则。运用联合仿真的方法进行了多种典型工况下汽车操纵稳定性仿真试验。结果表明：所设计的ESP模糊控制系统能有效地提高车辆在极限工况下的操纵稳定性。%For enhancing the vehicle handling stability,a vehicle dynamics model was established based on the multi-body dynamics analysis software MSC.ADAMS/Car.According to the basic principle of vehicle stability control,the ESP fuzzy control system was designed and the relevant control rules were formulated under the environment of the Matlab/simulink.The vehicle handling stability simulation test was carried on under the various typical conditions,using the method of co-simulation.Results show that the designed ESP fuzzy control system can effectively enhance the vehicle handling stability in extreme conditions.
