Rotor Speed and Attitude Control Method for Large-scale Rotor Test Bench

针对直升机旋翼风洞试验台旋翼运动控制的需求,采用高性能变频器以及独立式位置控制器完成系统硬件搭建,并基于LabWindows/CVI开发平台设计旋翼系统控制软件,软件实现转速高精度控制以及旋翼操纵装置中电动缸的运动控制。利用4m直径旋翼模型在FL-10风洞开展了试验验证。实际应用表明,该系统响应速度快,运行效率高,额定转速下控制精度达0.03%、总距控制精度达0.1°,满足直升机旋翼气动力风洞试验对控制精度的需求。

For the demand on rotor motion control of the helicopter rotor wind tunnel test bench,high-performance frequency converter and independent position controller are used to build the construction of system hardware platform,and rotor control system software is designed based on LabWindows/CVI.The software performs high precision control of the speed and motion control of the electric cylinder in control device.Φ4m rotor model is used to carry out test verification in FL-10 wind tunnel.The practical application shows that the system has fast response speed,high operating efficiency,control accuracy of 0.03%at rated speed and total pitch control accuracy of 0.1°,which meets the requirements of helicopter rotor aerodynamic wind tunnel test for control accuracy.
