Research on Dual-Variable Integrated Electro-Hydrostatic Actuator
Chinese Journal of Aeronautics, 2006 AbstractThe integrated electro-hydrostatic actuator (EHA) with variable displacement and variable rotation speed is researched. In the system, the output of the actuator is changed by controlling the rotation speed of the brushless DC servomotor and the displacement of the servopump. The mathematical model described in state space model is created. The
