摘要:
针对磁流变阻尼器在冲击缓冲系统中的应用,该文对其控制方法进行理论和实验研究。设计了冲击载荷下磁流变后坐缓冲试验系统,通过磁流变阻尼器的动态试验分析选定控制区域,提出将磁流变阻尼器多项式动力学模型应用于缓冲系统的仿真建模以及输出电流的反解,分别设计了一维和二维模糊控制器。用两种量化的充满度评价后坐缓冲的控制效果,仿真和试验结果表明,相对于原始后坐缓冲效果,磁流变后坐缓冲装置在模糊控制作用下的充满度指标明显提高,其中二维模糊控制效果较一维模糊控制效果更优。
Abstract:
To make sure that a magnetorheological fluid(MRF)damper can work well in a shock isolation system,theoretical and experimental investigations on control methods for the MRF damper are made.An experimental setup for recoil system utilizing a MRF damper is designed and manufactured.By analyzing the results of dynamic experiment,the control range is selected.A polynomial model of the MRF damper is introduced to be applied to the shock isolation system for simulation and inverse solution.A one-dimensional fuzzy controller and a two-dimensional fuzzy controller are both designed.The performance of degree of filling(DOF)is quantified by using two definitions.The results of simulations and experiments both indicate that DOFs of the MRF recoil isdation device with the two fuzzy controllers are obviously improved compared with the results of the original recoil isdation device.The two-dimensional fuzzy controller is more favorable for shock isolation than the one-dimensional fuzzy controller.
