Quadrotors UAVs Swarming Control Under Leader-Followers Formation

Unmanned Aerial Vehicles (UAVs) swarming has took an important part of the recent researches. Multiple robots offer many advantages when comparing to a single one such as reliability, time decreasing and multiple simultaneous interventions. This paper proposes a new scheme for trajectory tracking of multiple quadrotors UAVs under a centralized leader-followers formation strategy. Attitude stability and position control are assured using a double loop control structure based on the Linear Quadratic Regulator (LQR), moreover the leader-followers formation is maintained via a Sliding Mode Controller (SMC) controller. Many scenarios are proposed within this work. Simulation results proof the energy optimization and formation controller's robustness and accuracy.
