摘要
为了提高整车主动悬架的控制效果,应用汽车动力学理论在ADAMS/View中建立了简化七自由度整车主动悬架模型,利用经典PID控制原理设计了整车主动悬架控制器。将整车模型以模块化的形式导入到MATLAB建立的PID控制器中,建立整车主动悬架控制系统。仿真结果表明:与被动悬架相比,PID控制的主动悬架对车身的垂直加速度、俯仰角加速度及侧倾角加速度产生了有效的控制效果,提高了汽车行驶的平顺性。
In order to improve the control effect of automotive active suspension, the simplified Seven-DOF active suspension model was created in ADAMS/View by applying the dynamics theory, and classical PID control principle was utilized to design an active suspension controller for vehicle. The vehicle model was imported into the PID controller established in MATLAB as a module to create a vehicle active suspension control model. According to the simulation results, compared with passive suspension, the PID control of active suspension can control effectively the vertical vibration acceleration, roll and pitch acceleration of body, and this approach improved vehicle ride comfort performance.
