| Abstract: | Using the polynomial model as the dynamics model of magneto-rheological damper,the bad effect of the damping force jump with the "on-off" semi-active control on vibration acceleration of vehicle sprung mass is investigated.The simple fuzzy semi-active control and self-adaptive fuzzy neural networks semi-active control for 1/2 vehicle model with MR damper are researched,and the simulation is done.The results show that the semi-active control strategies can take better effect in decreasing vibration than the passive control for MR damper,and all are semi-active control,but the self-adaptive fuzzy neural networks control and the simple fuzzy control are better than the "on-off" semi-active control,and the self-adaptive fuzzy neural networks control is better than the simple fuzzy control. |
