摘要
为了满足长途运输时重型卡车行驶的平顺性要求,利用基于线性矩阵不等式(LMI)的H2控制算法对驾驶室安装了主动悬置的六自由度1/2重型卡车模型进行振动控制,所采用的路面激励为积分白噪声随机路面激励.大量的仿真结果显示,主动控制悬置系统明显降低了驾驶室的俯仰角加速度和俯仰角,采用主动控制悬置系统可有效地改善卡车行驶平顺性和乘坐舒适性.
In order to meet the ride comfort of the heavy truck cab when on line-haul, the H2 control algorithm based on the linear matrix inequalities （LMI） is presented for the active control of a 6 degree-of-freedom half- heavy-truck suspension system model . The road disturbance is integral white-noise stochastic signal. Numerical simulation results demonstrate that active suspension with a proper control strategy can decrease the roll angle and roll angle acceleration of the truck cab, the active suspension can improve both the ride comfort and driving safety.
