Modeling and control system designing of a morphing micro aircraft

A new method was presented for the dynamic modeling and control system designing of a morphing micro aircraft with variable sweep. Through operating point selecting, aerodynamic calculation and data fitting, dynamic model of the morphing aircraft was established. According to the characteristics of dynamic model, a flight control system design method was put forward based on parameter space approach for morphing aircraft. With computer aided design method, a longitudinal control system was designed. The simulation results show that the designed public fixed-gain controller can make the morphing aircraft have required dynamic characteristics in different flight stages, and show its feasibility and practicability.
