The design theory and key technology of a three-axis precise test turntable for antenna testing are described.Backlash of turntable transmission chain,processor speed and precision,control algorithm, control parameters,and operation capability of controller are the important factors that affect dynamic per-formance and stable precision.In order to improve dynamic performance and steady-state pointing precision, a dual-motors digital control system based on floating-point DSP and intelligent PI arithmetic is designed. The shafting precision of the system is analyzed and error compensation is made.Actual operations show that the control system can work stably and reliably and has high positioning accuracy,meeting the design techni-cal requirements.
