摘　　要：自动驾驶仪是导弹制导与飞行控制系统中的重要组成部分之一;驾驶仪的动态测试主要是检查各组件工作的正确性、可靠性以及组件之间配合的协调性;对动态测试原理进行了分析;提出了利用PXI总线的通用测试仪器,结合动态信号分析算法,实现动态测试的方法,并进行了方案验证;搭建了自动驾驶仪动态测试系统,实现了对自动驾驶仪功能的动态测试;分析了系统中可能存在的误差并阐述了改进的方法;该方法的测试精度与传统台式仪器相当,能够满足装备动态测试的要求。Autopilot is one of the important components of missile guidance and flight control systems.The dynamic test of the pilot is mainly to check the correctness,reliability and coordination of the components.The dynamic test principle is analyzed.A dynamic test method using universal test instruments of PXI bus is proposed,combined with dynamic signal analysis algorithm to realize dynamic test method,and the scheme is verified.The autopilot dynamic test system is built,and the dynamic test of the autopilot function is realized. Analyzed the possible errors in the system and explained the improved method.The test accuracy of this method is comparable to that of traditional benchtop instruments,which can meet the requirements of equipment dynamic testing.
