Abstract


Model and control of unmanned gyroplane should be studied in order to realize autonomous flight. In this paper, taking a type of unmanned gyroplane as the research object, mathematical model of unmanned gyroplane, flight control strategies and flight control system design and implementation were studied deeply.Firstly, the principle of rotor autorotation without power driving was studied by using the knowledge of aerodynamics and kinematics. Mathematical model of unmanned gyroplane was built after taking model analysis on autorotation rotor, propeller, vertical tail and fuselage. The model of unmanned gyroplane was linearized through the small disturbance method. Stability and operating characteristic for longitudinal and lateral channel of unmanned gyroplane were discussed as well. Secondly, attitude control, heading control, height control, speed control and engine control were studied, and then control loop and control law were designed for unmanned gyroplane. There are two ways to realize height control, which are the use of pitch attitude angle and engine thrust. After analyzing characteristics of two ways, a new method for height control was proposed, that is a combination of the use of attitude angle and the engine. This combined control strategy decreased the shortcoming which existed in single attitude control or single engine control. Then a fuzzy adaptive PID controller was designed for parameter setting of the pitch attitude angle control system. Thirdly, the implementation technology of the flight control system onboard for unmanned gyroplane was studied and design of hardware and software have been completed, while the design process for the ground remote telemetry system was studied as well. Finally, hardware in the loop simulation system of unmanned gyroplane flight control system was built. The effective of control laws and control strategy that have been designed were verified by hardware in the loop simulation.Through the study of modeling and control for unmanned gyroplane, the model of unmanned gyroplane was built and control strategies for attitude control, heading control and height control were designed. Meanwhile, the flight control system including hardware and software design has been completed. Hardware in the loop simulation verified that flight control strategy is effective.
