| description | In order to solve problem of remote four-cylinder synchronous control of active platform and vertical external loading platform of 30 000 kN hydraulic support test bench, a remote multi-cylinder synchronous control system of hydraulic support test bench based on PXI platform and LabVIEW RT was designed. High frequency electro-hydraulic proportional directional valve is adopted as actuating element of hydraulic system of high lift cylinder, and high precision displacement sensor is used as feedback element of real-time closed loop system. Synchronization of the high lift cylinder is achieved by running fuzzy PID control algorithm in embedded real-time controller and real-time adjustment of opening of the proportional directional valve. The practical application shows that the maximum four-cylinder synchronization error of the system is 0.91 mm and the minimum error is 0.63 mm during the lifting process of movable platform of the hydraulic support test bench. |
