Rotor-craft style UAV, such as the quadrotor, has ribavirin coupon become increasingly popular with researchers due to its advantages over fixed-wing UAV.The quadrotor is highly maneuverable, can perform vertical take-off and landing (VTOL), and can hover flight capability.Nevertheless, handling the quadrotor complex, highly nonlinear dynamics is difficult and challenging.
A suitable control system is needed to control the quadrotor system effectively.Therefore, this paper presents a review of different controller design techniques used by researchers over the past years for the quadrotor rotational and translational stabilization control.Three categories are discussed: linear controller, nonlinear controller, and intelligent controller.
Based on their performance specifications, luce chandelier the system rise time, settling time, overshoot, and steady-state error are discussed.Finally, a comparative analysis is tabulated, summarizing the literature in the performance specifications described above.
