摘要:
电动负载模拟器可以模拟飞行器飞行过程中舵机承受的铰链力矩,是舵机测试和半实物仿真的关键设备之一。根据电动负载模拟器的组成及工作原理,建立了被控对象的参考模型,基于Narendra模型参考自适应控制理论,设计了力矩控制的模型参考自适应控制系统,在考虑舵机较大阶跃扰动的情况下,对加载系统进行了数字仿真,结果表明模型参考自适应控制方法将加载系统带宽从20 Hz提高到30 Hz,实现了电动负载模拟器的快速、高精度控制,验证了该控制策略的有效性。

Abstract:
The electric motor drive load simulator can simulate the hinge torque of the steering gear during the flight of the aircraft, which is one of the key equipment of the servo test. This paper bases on the composition and working principle of the electric load simulator, and based on the Narendra model reference adaptive control theory, the reference model of the controlled object is designed. Considering the large step disturbance of steer gear, the load simulator system the paper presented is simulated. The results show that the model can increase the bandwidth of the load system from 20 Hz to 30 Hz, realize fast, high-precision control of the electric load simulator, and improve the system's anti-perturbation performance effectively.
Key words:    motor drive load simulator    model reference adaptive control    Narendra
