Design of Autopilot Dynamic Test System

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.
