A preliminary study on the guidance and flight control system for a test model of the stratospheric airship is conducted, and the result is explained. The test model is intended to stay at the altitude of 4000m, within 1km distance from the indicated point. The longitudinal and lateral flight control systems are designed, and the performance is verified by simulations, which generally show good performances. The design method of the control systems are explained, and step responces and some simulation results for the position keeping are shown.
