Research on Adaptive Fuzzy-PID Control and Simulation of Vehicle Seat Suspension

  • 摘要: 为提高车辆座椅悬架减振性能,建立了简化的三自由度车辆座椅悬架模型,结合模糊控制与PID控制理论提出了座椅悬架自适应模糊PID控制方法。该方法中以座椅垂直振动速度的误差为控制参量设计了PID控制器,将座椅垂直振动速度误差及误差变化率作为模糊控制器的输入变量,利用模糊控制规则对PID控制器参数进行在线自调整。以C级路面白噪声随机信号为输入,利用MATLAB/Simulink对自适应模糊PID控制器进行了仿真。结果表明:相对于不加控制和PID控制的座椅悬架系统,自适应模糊PID控制方法可以明显改善座椅质心处的垂直振动加速度。
