自适应模糊控制方法在主动悬挂系统中的应用研究

摘要

In order to provide good performance in improving ride quality, we designed an adaptive fuzzy controller for vehicle active suspension systems, and this fuzzy control method can tune the parameters of the controller on-line. A quarter-car model is used for suspension analysis and simulations. The vehicle vibration and disturbance are reduced considerably with this fuzzy controller. It is also shown that the designed active suspension system shows robust performance with system model uncertainties.%提出了一种主动悬挂系统的自适应模糊控制方法，该模糊控制方法可以在线自适应调整模糊控制的有关参数。1/4车辆模型作为仿真对象，模糊控制器可以显著地减小车辆的振动及干扰，提高车辆的舒适性。仿真结果表明该模糊控制方法的有效性。另外，当主动悬挂系统模型参数发生变化时该模糊控制器表现出良好的鲁棒性。
