Abstract: At present, based on realtime requirement of threeaxis simulation turntable control  system, the control system of three-axis simulation turntable is introduced firstly and then, Using ”Windows+RTX”integrated software platform, the real time control software is designed and realized according to the basic principle of the RTX and particular requirements of the turntable control system. Experimental results show that the real-time control software of the threeaxis simulation turntable based on RTX fulfills the system design specification, and achieves high simultaneity, stability and reliability.

Key words: Three-axis table, Control system, Simulation, Real time extension
