Actuator is a very important part of vehicle active control suspension. Based on the analyses of traditional passive suspension and active suspension system, a novel vehicle active suspension with Electro-Hydrostatic Actuator (EHA) is put forward. The system consists of two parts: spring and actuator with variable control force. The actuator includes hydraulic cylinder, hydraulic pump, controller, etc. According to bond graph principle, bond graph model of EHA active suspension are built. In addition, sky-hook controller and fuzzy logic controller are designed and sky-hook control and fuzzy control active suspension are simulated using MATLAB tools. 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 control and fuzzy control active suspension with EHA provide better ride comfort and stability than passive suspension system.
