Design and Experiment of Flight Path Control System of Unmanned Autogyro

Abstract

This paper presents the architecture of flight tracking control system for unmanned autogyro, and designs the control law based on the control characteristics of unmanned autogyro. To reduce the lift force loss during turning and maintain the altitude, the feedforward control method of pitching rudder for propeller is adopted (during rolling); To reduce the influence of propeller anti-twisting effect on the roll attitude and course, feedforward control method of the propeller rolling rudder (during throttle changing, is adopted; to reduce the slide slipping and achieve coordinated turning, a hybrid control strategy of the yaw rudder and rolling rud-der of propeller is developed. The flying platform is built to verify the flying. It is proved that this control system can effectively control the altitude and horizontal path of the unmanned autogyro, the control accuracy is better than ± 5m.
