Abstract: The supervisory control system for a pump-control-motor composite hydraulic volumetric speed control system with variable frequency and displacement was researched. Based on the full introduction to the working principles about the experimental system and the supervisory control system's structure, the supervisory control platform was implemented with LabVIEW technology. The results indicate that the supervisory control system realizes the acquisition, preservation and processing of the data, including analog data, serial data and so on. At the same time, the control for the speed of hydraulic system was realized by adjusting frequency or variable displacement，and the electro-hydraulic load simulation was achieved by adjusting the proportional relief valve. The supervisory control platform with friendly man-machine interface has a good openness and extensibility,and performs reliably, which is able to meet the needs of dynamic parameter monitoring and automatic control for the hydraulic system better.

Key words: variable speed, variable displacement, hydraulic volumetric speed control system, supervisory control platform
