液压支架试验台远程多缸同步控制系统设计
Design of remote multi-cylinder synchronous control system of hydraulic support test bench
摘要
Abstract
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.关键词
