摘要
分析基于电流变阻尼器的半主动悬架系统,建立了1/4车辆状态空间模型,在路面输入是随机白噪声下,应用干扰抑制指标,设计H∞控制器,并且用MATLAB进行了数值仿真,与被动悬架相比,H∞控制下的闭环悬架系统能有效降低车身垂直加速度。
The quarter car state-space model is built for the analysis of a semi-active vehicle suspension system with ER damper. A H∞ controller is designed based on disturbance attenuation index under white noise road excitation and simulation is carried out using MATLAB. The closed-loop system with H∞ controller can reduce the vertical acceleration effectively compared to the passive suspension.
