| Abstract: | An electro-hydrostatic actuator was introduced into vehicle active suspension and the prototype structure of active suspension with EHA was proposed.Quarter-car model was set up in the form of differential equations and fuzzy logic controller was designed to control vehicle active suspension with EHA.Under a certain of road given,simulations were done.The result shows that active suspension with EHA using fuzzy control evidently improves ride comfort,handling and stability of vehicle. |
