Speed Control of Hydrulic Motor System with Swashplate DC-Controlled Pump

Abstract:

A swash plate pump-controlled hydraulic motor system has been presented in this work. The flow rate of the hydraulic motor system and then the output speed could be controlled by adjusting the swash plate angle. Actuating the swash plate using DC servomotor could enhance dynamic performance of the pump, and then better improve the performance of overall hydraulic motor system. In this study, another speed control configuration has been introduced and the angular velocity of hydraulic motor has been controlled using both PI (proportional and integral) and FL (fuzzy logic) controllers.
