Sky-Hook Control of Vehicle Active Suspension with Electro-Hydrostatic Actuator

Abstract:

A kind of vehicle active suspension based on Electro-Hydrostatic Actuator (EHA) is put forward. The suspension system consists of two parts: spring and actuator with controlled force. The actuator includes hydraulic cylinder, hydraulic pump, controller, etc. In this paper, a quarter-car dynamic model is exactly established involving bond graph models of EHA parts. Under the input conditions of the given road profile and designed sky-hook controller, The prototype and test rig of EHA active suspension are developed and bench tests are carried out. The simulation and experimental results show that sky-hook active suspension with EHA provides better ride comfort, handling and stability than passive suspension.
