A robust pitch autopilot design scheme is proposed for a morphing unmanned aerial vehicle. Autopilot during wing transition phase is designed considering the properties of system change with time. To maintain the uniform characteristics of the closed-loop system, input-output pseudo-linearization scheme is adopted. Moreover, a novel coordinate transformation is proposed so that the system satisfies the matching condition after the coordinate transformation. Extended state observer is designed to recover flight control performance even in uncertain environment. Numerical simulation demonstrates the effectiveness of the proposed controller during the wing transition phase.
