In order to achieve lowspeed performance of high power hydraulic motor speed system as well as to balance the conflict between efficiency and response, a valvepump parallel control system for hydraulic motor speed regulation was proposed. LabVIEW was used to monitor and collect data of the experimental system. The results show the hydraulic motor speed system has preferable performance on low speed stability, and strong robustness on load disturbance, thus offer a good option for speed.
