摘要
针对采用磁流变阻尼器的1/4汽车半主动悬架模型进行振动控制分析。利用迭代线性矩阵不等式(ILMI)算法在输出反馈控制中的求解优势,提出基于ILMI算法的半主动悬架静态输出反馈控制方法。仿真结果表明,结合合适的控制算法,采用磁流变阻尼器的半主动悬架系统有效地改善了汽车驾驶平顺性和乘坐舒适性。
A vibration control analysis is conducted on a quarter model for the semi-active suspension of a car with magnetorheological （MR） damper. Taking the advantage of iterative linear matrix inequality （ILMI） algorithm in solving output feedback control issues, a static output feedback control method based on ILMI algorithm is proposed for semi-active suspension and a simulation is performed. The results show that with a proper control algorithm, the semi-active suspension with MR damper can effectively improve the ride comfort of vehicles.
