摘要

Ornithopters, unmanned air vehicles flying using flapping wings to generate thrust, are analyzed for forward flight. The Newton method has been used to calculate flight trajectories at a specified average velocity. These trajectories are analyzed for stability, and linearized models of the dynamics are generated for control design. Several controllers are tested, all of which were capable of stabilizing unstable limit cycles of ornithopter flight. Among these controllers are the proportional-derivative controller; the state feedback periodic discrete-tune time-varying linear quadratic regulator; and the sensor feedback, periodic discrete-time time-varying linear quadratic Gaussian regulator. The periodic discrete-time controllers are shown to decrease tracking errors associated with constant-gain controllers on time-varying systems.
