    Abstract
  • The fuzzy robust tracking controller within full envelope of unmanned aerial vehicle (UAV) was proposed for the problems of wide variation of aerodynamic characteristics, experiencing parameter uncertainty and external disturbances during the flight in large envelope. With fuzzy c-means clustering, the fuzzy T-S model approximating the dynamics of UAV within full envelope was constructed. Based on the augmented tracking system of airspeed and altitude, the constraint condition of fuzzy robust tracking controller was provided in terms of linear matrix inequalities (LMI) according to guaranteed cost theory with descriptor system based fuzzy Lyapunov function approach, and input-states stability was ensured. The control parameters were optimized via minimizing disturbance attenuation with less conservative and reduced computation complexity. The simulation shows that high accuracy tracking of airspeed and altitude desired instructions within full envelope is realized with strong robustness to parameter uncertainties and external disturbances.
