摘　　要：为了克服某高超声速风洞五自由度机构控制系统功能单一、精度低、运行可靠性差等缺点,对其控制系统进行了重新研制。新的控制系统采用模块化设计,以DMC-2180独立型多轴运动控制器为核心,通过PDC系列直流伺服单元,连接5台直流伺服电机,并通过绝对编码器反馈机构位置,从而构成高精度的闭环直流伺服控制系统。控制软件采用运动控制器自带的GALIL两字符命令集同时结合VB/VC++语言等编程方式,实现了多种运动控制功能。经过调试并结合几年来的运行实际情况表明,该控制系统精度高、运行稳定可靠、设计先进、功能齐全。In order to overcome the defect of control system of five-degrees of freedom mechanism in the hypersonic wind tunnel such as single function,low precision and reliability,a new control system was developed. The DC servo control system was composed of DMC-2180 unaided multi-axis locomotion controller,5 PDC DC servo cells,DC motors and absolute encoders. Computer control software adopted GALIL two-characters command and VB / VC ＋＋. It has proved that the control system has many characters such as high control precision and stabilization,advanced design method and perfect function. We mainly introduced technique target,design scheme,hardware structure,software development and application effect of it.
