Abstract:
A semi-active force tracking PI controller is formulated and analyzed for a magnetorheological(MR)fluid-based damper in conjunction with a quarter-vehicle model. Two different models of the MR-damper are integrated into the closed-loop system model, which includes: a model based upon the mean force-velocity (f -v) behaviour; and a model synthesis comprising inherent nonsmooth hysteretic force and the force limiting properties of the MR damper. The vehicle models are analyzed to study the vibration attenuation performance of the MR-damper using the semi-active force tracking PI control algorithm. The simulation results are also presented to demonstrate the influence of the damper nonlinearity, specifically the hysteresis, on the suspension performance. The results show that the proposed control strategy can yield superior vibration attenuation performance of the vehicle suspension actuated by the controllable MR-damper not only in the sprung mass resonance and the ride zones, but also in the vicinity of the wheel-hop. The results further show that the presence of damper hystersis deteriorates the suspension performance.
设计了一种半主动力跟踪PI控制器, 对由磁流液(MR)阻尼器作为悬架阻尼器的汽车模型进行控制分析.MR阻尼器的2种不同模型在闭环的汽车悬架控制系统模型中得到了应用.2种模型是基于均值阻尼力对速度(f-v)特性的均值f-v模型, 和描述阻尼力非光滑滞环和饱和特性的滞环f-v模型.汽车模型用来研究力跟踪PI控制算法和MR阻尼器对车辆的振动抑制性能.仿真分析还指出了MR阻尼器的非线性, 特别是滞环特性对汽车悬架系统的性能影响.结果表明所提出的控制方法对由MR阻尼器驱动的汽车悬架系统能产生很好的减振效果, 不仅体
