| 摘 要： | 采用1/4车模型对阻尼在振动中的作用进行了分析,提出了一种充分利用阻尼消耗振动能量,通过阻尼控制降低悬挂质量加速度峰值的半主动悬架模糊控制策略,建立了参数自整定模糊控制器.ADAMS、Matlab/Simulink联合仿真结果显示,与实际非线性阻尼特性的被动悬架和现有模糊控制相比,基于该策略的控制器对车辆平顺性和操稳性有明显改善作用.

| Abstract: | The effect of damping on vibration is analyzed during the suspension deformation based on the 1/4 vehicle model. The Fuzzy logic control strategy for the semi-active suspension was proposed. By means of dissipating the energy of vibration and decreasing the peak value of the body acceleration via the action of damping, the parameter-self-adjust fuzzy controller was established. The united simulation of ADAMS and Matlab/Simulink were used for demonstrating the efficiency of the controller. Comparing with the practical passive suspension possessing the nonlinear character and the present fuzzy controller, the control system based on the new-style strategy provides better ride comfort and road handling. |
