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.
