Gain schedule control of morphing vehicle based on switched polytopic system

Considering morphing vehicles with alterable sweep wings, control design and synthesis within full flight envelope was researched. The morphing vehicle model based on switched polytopic systems was established. In this framework, the stability analysis was accomplished by Lyapunov functions. The presented approach can guarantee the flight stability of the morphing vehicle within full flight envelope. A technique using the small convex hull algorithm was provided to select operating points from the 3-D flight envelope. Optimal control laws were also designed for linear models of operating points. To inherit the advantage of traditional methods, a specific interpolation method was proposed to make the control synthesis within the 3-D flight envelope brief and practical. Simulation results show that the proposed approach can guarantee flight performance during the fast reshaping of the morphing vehicles within full flight envelope.
