摘要
介绍了一种在无人飞行器中设计应用的伺服系统余度控制接口,该接口实现了数字总线和模拟量两余度接口控制,可有效提高伺服系统的可靠性和抗干扰能力;分析了无人飞行器机载伺服系统的结构组成和工作模式,选择了CAN总线作为机载数字通讯总线,论述了机载伺服系统余度控制接口的工作原理,同时给出了伺服控制器的硬件接口电路及软件工作流程;实验结果表明余度控制接口工作稳定,控制通道转换平稳,该接口能满足无人飞行器控制系统的要求。
The paper presents the servo system redundancy interface applied in UAV, digital bus and analog dual--redundancy control interface is implemented, so the rehahility and the antijamming capability of servo system are made to he promoted. CAN bus is chosen to be the UAV digital bus after analyzing the structure and the operate mode. The operating principle of redundancy interface is expatiated, the hardware interfaces and the software process are provided. The results of experiments indicate that the redundancy interface works steadily and channel switchs smoothly, it can meet the needs of UAV flight control system.
