模糊控制器在车辆稳定系统中的设计应用

The Design and Application of Fuzzy Controller in the Vehicle Stability System

针对车辆安全稳定系统的算法设计中加载于车身的横摆力矩值如何确定的问题,建立了以隶属度函数和运算规则为基础的模糊控制器。本文简述了模糊控制器的一般组成,并阐明此系统控制器针对的输入参考对象是车辆质心的横摆角速度偏差,再通过描述车辆安全稳定控制系统的流程和系统的模糊控制原理设计了需要的隶属度函数和模糊子集。最后,设计了输出力矩的模糊运算规则以满足系统的实际需要。

The fuzzy controller which is based on the membership function and rules is established for the algorithm design in the vehicle safety and stability systems.The composition of the fuzzy controller is summarized,and it is illustrated that the vehicle yaw rate deviation of the mass center is this controller＇s input reference.Through the describing of the process of the vehicle safety and stability system and principle of the fuzzy controller,the membership functions and the fuzzy control sets are designed.Finally,the rules of the fuzzy controller are made to meet the needs of the actual system.
