基于CMAC的半主动车辆座椅悬架系统研究

o improve the seat anti-vibration effect of truck and engineering vehicle, a semi-active seat suspension system is constructed by using magneto-rheological (MR) damper to replace the passive damper of traditional seat suspension. A human-body-seat seven-DOF multi-body dynamics model is established and its corresponding CMAC and PID controller is designed. The simulation is completed by the random roughness of road surface input model. Simulation results show that CMAC and PID scheme can effectively attenuate the vertical vibration acceleration and increase the riding comfortableness.
