摘要： 建立了含驾驶室的商用车十自由度整车数学模型，对安装了驾驶室有限带宽主动悬置的商用车进行模糊控制系统设计，该控制系统全面考虑了驾驶室质心处垂直、俯仰、侧倾方向振动，并采用遗传算法对模糊控制器增益因子进行优化．以积分白噪声随机路面输入作为激励进行振动仿真，仿真结果表明采用本文设计的驾驶室有限带宽主动悬置模糊控制系统相对全浮式悬置系统有效降低了驾驶室质心垂直、俯仰和侧倾加速度，一定程度上提高了商用车行驶平顺性和乘坐舒适性．

Abstract: A ten-degree-of-freedom mathematical model of a commercial vehicle including the cab was established. Based on fuzzy control theory， a bandwidth-limited active control system for the commercial vehicles cab suspension was designed. The vibrations of center of mass were investigated in directions of heave, pith and roll. The gain factor of fuzzy controller was optimized through genetic algorithm and the vibration was simulated using integral white noise random road as input.The results show that by employing the bandwidth-limited active control system proposed， the heave angular acceleration， pith angular acceleration and roll angular acceleration are distinctly reduced when compared with that adopted full floating suspension system. Meantime， the ride performance and comfortability of the commercial vehicle are improved．
