Abstract :
In this paper, an electrically driven variable displacement servo pump was designed to meet the requirement of dual-variable control in integrated electro-hydrostatic-actuator. The driving force of variable displacement mechanism of the servo pump was analyzed, and the mathematical model was created. A DC servo motor was selected as the executive unit of the variable displacement mechanism, the structure of the mechanism that drives the swashplate and the digital controller using digital signal processor (DSP) was designed.
