| 中文摘要: |
| 建立了1/2车辆主动悬架系统动力学模型和路面输入模型,将PID控制和模糊控制并联,设计了主动悬架系统模糊PID控制器.在MATLAB/Simulink中的仿真结果表明,模糊PID控制的主动悬架在车身加速度、俯仰角加速度、悬架动行程及轮胎动位移等方面明显优于被动悬架以及单纯的模糊控制和PID控制,较好的改善了车辆的行驶平顺性及乘坐舒适性. |
| 英文摘要: |
| 1/2 active suspension of vehicle system dynamics model and road input model were established.The PID control and fuzzy control were parallel connected and the active suspension with fuzzy PID controller was designed.The simulation results in MATLAB/Simulink showed that the active suspension fuzzy PID control was superior to the passive suspension and simple fuzzy control and PID control in the aspecls of vehicle body acceleration,pilch angular acceleration,suspension dynamic travel and tire dynamic deflection,the riding comfort can be improved preferably. |
