【摘要】 基于模糊控制理论设计了一种模糊自适应ESP控制器,该控制器可根据反馈的车辆状态信息自动适应车速和路面附着系数的变化。采用Matlab/Smulink建立了14自由度车辆模型和控制器模型,考虑了轮胎的非线性特性对汽车转向特性与行驶稳定性的影响。仿真结果表明,该控制器能够提高汽车在高速或光滑路面上的操纵稳定性,有较强的适应性和鲁棒性。更多还原

【Abstract】 A kind of self-adaptive fuzzy ESP controller was designed based on fuzzy control theory,which adapted to the changes of the vehicle speed and the road adhesion coefficient according to vehicle information.The vehicle model with fourteen degrees of freedom and controller model were set up by using Matlab/Simulink,and the influence of nonlinear characteristics of tires on cornering characteristics and driving stability of vehicle was considered.The simulation results showed that handing and stability of vehicle on the high-way and slippery road can be improved by self-adaptive fuzzy controller.The controller demonstrated a good stability and robustness.更多还原
