【摘要】 针对整车悬架大系统模型的特点,运用智能分布式递阶控制策略建立了汽车半主动悬架系统的控制结构;在整车动力学模型的基础上,设计了基于整车车身姿态协调控制的仿人智能控制器,对不同的车身运动姿态采用不同的控制模态,并以某车型为例对其进行了控制仿真。仿真结果表明,对整车半主动悬架进行分布式协调控制是可行的,且相对于被动悬架及采用集成控制策略,分布式智能协调控制能更好地提高车辆的平顺性能,并能有效抑制车身俯仰和侧倾运动,改善轮胎的接地性能。更多还原

【Abstract】 According to the characteristics of the large scale model of the full vehicle suspension system,using the strategy of intelligent distributed hierarchical control,the control structure of semi-active suspension system was established.Based on the full vehicle dynamics model,the controller of Human-like Intelligent Control(HSIC) based on full car body poses coordinating control was designed.According to different motion poses,a corresponding control mode was selected.A light-duty vehicle as an example,the control model was simulated.The result of simulation shows that the intelligent distributed hierarchical control strategy of semi-active suspension to full car is feasible.Compared to the passive suspension and the integrated control strategy,the intelligent distributed hierarchical control can achieve good ride comfort,restrain pitch and roll motion and improve stability than them.更多还原
