【摘要】 在建立了汽车主动悬架与转向系统集成控制模型的基础上,应用LQG控制理论,设计了汽车主动悬架与转向系统LQG集成控制器,并进行了试验仿真,实现了对质心侧偏角、车身横摆角速度、车身垂直加速度、车身俯仰角的集成控制。与被动悬架和转向系统、主动悬架与转向系统单独控制相比,汽车的平顺性、操纵稳定性和安全性都有了显著改善,为汽车底盘集成控制研究提供了依据。更多还原

【Abstract】 This paper established the integrated control model of vehicle active suspension and steering system,adopted LQG control theory,designed the LQG integrated controller of vehicle active suspension and steering system and simulated the controller,realized the integrated control of vehicle slip,yaw velocity,bouncing acceleration and pitching velocity.Compared to the passive suspension and steering system and to the active suspension and steering system control independently,the performance of steer smooth,control stabilization and security are all distinct improved.Provided the proof to the study of vehicle chassis integrated control.更多还原
