Paper Title:
The Time-Delay Study on Vehicle Active Control Suspension
  Abstract

Actuator is a key factor for vehicle active suspension. A new vehicle active suspension is put forward based on the Electro-Hydrostatic Actuator (EHA).For vehicle active suspension system, unavoidable time delay may appear in the controllable course. The critical time-delay of EHA active suspension is calculated in this paper and time-delay influence on the dynamic performance of vehicle active suspension is analyzed. A time-delay compensation strategy for EHA active suspension is proposed to reduce time delay. A self-adapting fuzzy controller is designed and applied to active suspension system with EHA. Physical prototype and experimental rig for EHA active suspension are built. Then time-delay tests of suspension prototype are carried out on the developed test rig. Test results show that the sprung mass acceleration of the active suspension with time-delay compensation significantly declines by 12.4% under the road input of 1.2Hz and by 13.6% under the road input of 1.6Hz.
