In this research, we develop an unmanned airship system. In addition to the traditional Remote Control system a PC-based flight control system was developed to improve flight stability and maneuverability.
The system includes two parts: the vehicle and the ground control console. The vehicle consists of an envelope, a gondola, a pair of elevator and rudder, a thrust-vector system and a flight control unit. The ground control console consists of a control joystick and a notebook, which is used to input control command and to monitor the airship. Both of them are PC-based, and we can easily change their behavior by modifying the software. The technology developed in this research can be applied to other unmanned systems.
In this research we analyze the flight dynamics of the airship and establish the governing equation. The system parameters are obtained partly by direct measurement of the airship and partly by compare other similar airships. A height and pitch control law is designed based on this model. To simplify the design process, we decouple the system and design controllers to stabilize vehicle motion and pitch motion separately. The control gains are adjusted based on numerical simulation and real flight test.
Real flight tests have shown that the height and pitch angle of the airship has been successfully kept in the reasonable range of the set values.
