摘　　要：设计了复合舵机直线加载实验台,包括油源、油源控制器、舵机控制器、复合舵机、加载舵机、加载惯量盘以及支撑台体等。油源控制器采用AVR128单片机作为核心控制芯片,控制系统软件使用NI LabWin-dows/CVI和Microsoft Windows操作系统的实时扩展RTX实现实时控制。加载通道的齿轮齿条惯量盘可以模拟飞机舵面的转动惯量,并且可以使用配重块调节转动惯量。该实验台既可以作为复合舵机设计、性能评价的半实物仿真平台,也可以用于本科生、硕士研究生相关课程的实验。A compound actuator linear loading test stand is designed including a hydraulic power supply, a con-troller of hydraulic power supply, a compound actuator, a loading actuator, loading moment of inertia and platform of supporting. The AVR128 single chip is the core chip of the hydraulic power supply controller. Using NI LabWindows/CVI and the real-time extension （RTX） for Microsoft Windows realizes real time con-trol. The inertia discs, which are driven by rack and pinion in the loading channel, can simulate aircraft rud-ders inertia. What is more, the moment of inertia can be adjusted by using weights. The test stand can be used not only as a platform of hardware in loop for a compound actuator design and its performance evaluation but also as experiments of related courses for undergraduate and graduate students.
