Adaptive backstepping controller design of quadrotor biplane for payload delivery

Performance of the UAVs for a particular application can be enhanced by hybrid design, where take-off, hover, and landing happen like rotary-wing UAVs, flies fixed-wing UAVs. A backstepping controller an adaptive are designed trajectory tracking payload delivery in medical emergency or substance vaccine presence wind gust. Simulation results show that effectively tracks during entire flight envelope, including hovering, transition phase, level mode, landing. comparison between Backstepping, Integral Terminal Sliding Mode (ITSMC) Adaptive Backstepping controllers altitude attitude. ITSMC is capable desired change mass but has sluggish response. The generates steady-state error biplane quadrotor.
