本文重点研究了四分之一汽车悬架采用磁流变液阻尼器的几种外环控制器设计的性能评价。采用Magne-Ride阻尼器，并以力-位移和力-速度特性的形式研究其行为。阻尼器的非线性滞回行为采用六阶多项式模型建模。力跟踪控制进行检查力跟踪能力的阻尼器使用PI控制。建立了运动控制方程，并与天钩控制相结合。Skyhook政策，然后适应在模糊逻辑控制的发展，以提高乘坐性能。在时域上比较了模糊逻辑控制与开关型和连续型天棚控制的性能。仿真结果表明，基于Skyhook算法的模糊逻辑控制具有较好的控制性能。
This paper focuses on performance evaluation of several outer loop controller designs employed in a quarter car suspension featuring a magnetorheological fluid damper. A Magne-Ride damper was employed and its behaviour was investigated in the form of force-displacement and force-velocity characteristics. The non-linear hysteretic behaviour of the damper was modelled using a sixth order polynomial model. Force tracking control was performed to check the force tracking ability of the damper using a PI control. The governing equations of motions were formulated and integrated with skyhook control. Skyhook policy was then adapted in the development of a fuzzy logic control to enhance the ride performance. The performance of fuzzy logic control was compared with the on-off and continuous skyhook control in time domain. The results show that skyhook algorithm-based fuzzy logic control gives better performances than its counterparts.
