摘　　要：有关磁流变阻尼器的控制系统的控制算法有很多,首先建立了基于磁流变液特性的Bingham动力学模型,然后针对磁流变阻尼器分别设计了Heaviside函数控制器、Sigmoid函数控制器、直接模糊控制器和模糊PI控制器,最后将Bingham模型和以上四种控制器分别在Simulink软件中构建闭环控制系统并进行仿真分析,根据其控制效果,并结合工程实现的可行性,得出了模糊控制是针对磁流变阻尼器的一种理想的控制算法的结论。There are many control algorithms about MRD（Magnetorheological Damper） control system, first of all, this paper establishes the Bingham model based on the characteristics of MRF（Magnetorheogical Fluid）, after that, we design the Heaviside functional controller, Sigmoid functional controller, fuzzy controller and fuzzy PI controller, finally, we build a closed-loop control system that include the Bingham model and the four controllers above and analyze the simulation result in the Simulink software. From the control effect and its engineering feasibility, we can get the conclusion that fuzzy control is an ideal control algorithm for MRD.
