| 摘 要： | 在MATLAB／SIMULINK中建立了七自由度车辆主动悬架模型，以提高车辆行驶平顺性为控制目标，主动悬架作动器的输出力为控制对象，根据最优控制原理设计出了基于轴距预瞄信息的主动悬架控制策略．仿真结果表明，与无预瞄系统的控制策略相比，基于预瞄信息的最优控制策略能够有效地降低车身垂直振动加速度、车身侧倾角加速度和俯仰角加速度，车辆行驶平顺性明显提高．

| Abstract: | An active suspension system with 7-degree freedom is established based on MATLAB/SIMULINK.Aiming at improving the ride comfort and slecting the actuator outputing force as a contorl object,the control strategy with preview information of linear-quadratic regulator(LQR) for the active suspension is proposed.As the simulation result shows that vertical vibration acceleration,roll and pitch acceleration of the vehicle are reduced in contrast with the control strategy without preview,and the property of the aut... |
