| 摘 要： | 建立了半车三自由度汽车转向与主动悬架的综合模型，以提高汽车行驶平顺性、操纵稳定性和安全性为出发点，采用基于小波理论的最小均方（LMS）算法对转向与主动悬架集成系统进行控制．计算结果表明：采用LMS控制的转向与主动悬架集成系统可使车身垂直加速度、车身横摆角速度、车身俯仰角和前后悬架动挠度等性能参数得到优化，汽车行驶平顺性和操纵稳定性比被动系统明显改善，有效地提高了汽车综合性能；与基于全反馈控制的集成系统LQG控制器相比，LMS能自动调整权系数且控制算法简单，便于工程应用．

| Abstract: | A 3D half vehicle model of steering and active suspension system has been established.By using least mean square(LMS) arithmetic based on wavelet theory the integrated system of steering and active suspension is controlled to improve vehicle maneuverability,handiness and safety.As a result the vehicle performance parameters are optimized and the vehicle integrated performance is improved obviously.Compared with LQG controller system,the algorithm is simpler to adjust coefficient automatically,and practical to engineering.vehicle;active suspension;steering system;integrated system;wavelet theory;LMS arithmetic |
