2.4m跨声速风洞双转轴控制系统

Control System of Double-Roll Mechanism of 2.4m Transonic Wind Tunnel

由于原双转轴控制系统无法满足风洞试验使用要求,重新研制出采用"工控机+手操器+运动控制卡"控制方案的双转轴机构控制系统。新系统由独立型运动控制卡、伺服驱动器、上位计算机、智能远程手操器构成。分别介绍了控制系统硬件总体方案和双转轴控制系统软件设计。新研制系统可分别在控制间通过上位PC机和在风洞试验段现场通过智能手操器进行精确控制,并已投入风洞型号试验近2年。实际应用结果表明:新系统达到了控制精度要求,在操作便利性及可靠性方面有较大的提升。

As the previous control system of the double-roll mechanism could not meet the requirement of wind tunnel testing,a new control system which consists of standalone motion control card,servo amplifier,epistatic computer and intelligent remote operating panel was developed.The overall hardware scheme and the software design are described respectively.The new system can be operated through PC in the control room and through the intelligent remote operating panel in the test section respectively and has been put into operation for about 2 years.Its application in the wind tunnel testing shows that the control precision can meet the system requirement.The operating convenience and system reliability has been evidently enhanced.
