In this article,a flight control system for unmanned airship based on ATmega2560 as the master chip,and MPU6050 as inertial measurement unit is developed aiming at the problem of the constitution and features of unmanned airship.The whole structure and the disigh of software and hardware are introduced in detail.Including IMU module and motor conteol module.The software flowchart is also presented.The airship flight attitude flight path and feedback volume have been simulated by building the ground real-time simulation environm ent.The simulation results have proved that the speed and accuracy of flight control system is high. This controler is verified by unmanned airship,The experiments shows that the design of the flight control system is reasonable and it satisfies the performance requirements of the unmanned airship and further engineering applications.
