设计并研制了一种基于RTX实时扩展模块的2.4 m风洞虚拟飞行试验的舵机控制系统。该系统用于采集天平、陀螺仪、舵机、光电编码器信号,为飞机各主要部件的气动特性评估提供了重要依据。文中介绍了RTX实时模块和硬件设计、软件设计。并通过实际应用表明,该系统具有实时性强、算法可靠、精度高、用户操作简单等优点。

关键词: RTX, 驱动程序, PXI, 舵控仿真


This paper designs and develops a set of testing system for Steering Gear control of virtual flight test from 2.4 meter windtunnel based on RTX real-time extension module.The system which provides an important basis for the assessment of aerodynamic characteristics for flight major components collects Signals which are sent by Balance,Gyroscope,Steering Gear,photoelectric encoder.The paper introduces RTX real time module and hardware design firstly,and then describes the software design divided into 2 parts.Finally,in conjunction with a practical application,it is more time critical,more stable when running algorithm,higher accuracy and more user-oriented.

Key words: RTX;driver;PXI;steering gear control simulation
