| 摘 要： | 针对电动汽车底盘振动控制及其能量反馈的设计要求，建立其1/4馈能式主动悬架模型，从能量角度使用基于线性二次最优调节器(Linear Quadratic Regulator, LQR)的控制方法，使悬架在控制力作动下达到车身振动能量尽量小并获得一定的振动反馈能量.在理论分析基础上，使用与Simulink建立联合仿真系统，分析LQR控制器协调底盘在复杂工况下的振动控制及其能量反馈的综合效果.分析表明，所用LQR协调控制方法能有效协调减振及其能量反馈.

| Abstract: | The energy regenerative active suspension model for the electric vehicle is built. Based on the comprehensive design requirements for the coordination of vibration damping and energy regeneration, a coordinated Linear Quadratic Regulator (LQR) control law is utilized. The control model aims at minimizing the vibration, controlling force input and supplying energy regeneration. Based on the analysis, the computation model is built with Adams/View and Simulink to evaluate the effectiveness of the LQR controller for the vibration reduction and energy regeneration under complicated driving conditions. The results show that the proposed LQR control is effective in coordinating the vibration damping and energy regeneration. |
