A previous investigation into a two-stage controller with a stand-alone first stage showed that the modeled results for the real-time responses of the swashplate angle and for Bode plots agreed well with experiment (Lin and Akers, 1988). The current investigation shows the separate effects of feedback ratio and supply pressure on the pump’s dynamic behavior.
