主动悬架控制技术研究

摘要

根据主动悬架控制理论,本文在MATLAB/Simulink上建立1/4主动悬架模型,设计LQG控制与模糊逻辑控制的主动悬架,并进行仿真研究.仿真结果表明,经过LQG控制和模糊控制的主动悬架相对于被动悬架,车辆的平顺性、乘坐舒适性有较大的改善,使主动悬架具有良好的综合性能.%This paper builds 1/4 of an active suspension model in MATLAB/Simulink based on the active suspension control theory. After simulation focused on the active suspension with LQC controller and fuzzy logic controller, the results show that the controlled active suspension has a great improvement in ride comfort and can reach a better performance relative to the passive suspension.
