| Abstract: | A two degree of freedom platform which can realize pitching and rolling motion is introduced.The control system selects the ladder control method and the communication between the upper computer and the lower computer is realized through the Ethernet.The driving system uses the asymmetrical valve to control the asymmetrical hydraulic cylinder,uses the dynamic pressure feedback method to enhance damping ratio of the system,and therefore nonlinear characteristics of the system can be improved. |
