摘要
为了减小重型货车在转向操作时的侧倾角,从而避免货车转向时发生侧翻,可以通过在悬架中安装主动抗侧倾杆以补偿横向载荷转移的方法来实现。本文的分析为这一方法提供理论依据。运用基于线性矩阵不等式(LM I)的H∞控制理论,提出了基于观测器的抗侧倾输出反馈控制算法。通过对某具有一系列不确定性参数的重型货车侧倾-横摆动力学模型进行仿真,验证了此控制算法的有效性和鲁棒性。
For reducing roll angle to avoid roll-over of heavy truck during steering, an active anti-roll bar is installed in suspension to compensate lateral load transfer. The analysis in this paper provides a theoretical base for this method. By applying the H∞ control theory based on linear matrix inequality (LMI) approach, an observerbased output feedback anti-roll control algorithm is proposed. A roll-yaw dynamics model for heavy truck with a series of parameter uncertainties is simulated, the results verify the effectiveness and robustness of the control algorithm.
