【摘要】 为了经济而直观地比较模糊控制换挡变速的效果,设计在同一仿真平台下的多条件实验可以方便地实现。这里用MATLAB/SIMULINK建立了车辆传动系动力学仿真模型及模糊控制器模块,构造了规则可选的四参数(包括节气门开度、节气门开度变化率、车速、加速度)模糊换挡控制逻辑规则,建立了相应基于规则(诸如运动规则、雪地规则、经济性规则)的条件选择模块,搭建了车辆换挡的模糊控制仿真平台。在运动模式与雪地模式两种情况下进行了对比仿真试验,结果表明换挡仿真方法能够在没有循环换挡发生的稳定状态下真实、准确地反映两种模式的运行过程状态。更多还原

【Abstract】 For readily comparing the different fuzzy controller, only one simulation platform designed for several experiments is desirable. The dynamic model of vehicle powertrain and fuzzy controller was given and created in the MATLAB/SIMULINK. The controller employed a four-parameter (throttle, velocity of throttle, speed and acceleration) fuzzy shift controlling. The different controllers were constructed with different shift principles including sport rule, snow rule and economic rule in this fuzzy shift platform. A contrasted test of simulation based on sport principle and snow principle shows the stability of shifting state without shift loop.更多还原
