Abstract

An autonomous quadrotor is an aerial helicopter with four horizontal rotors designed in a square configuration capable of locating lost or jeopardized victims, gathering military intelligence, and surveillance. Controlling of unmanned quadrotor is an interesting problems for control researchers. The literatures as assume a linear model and control it about operating point using the RPM , thrust, and torque In this paper, the proposed controllers are utilized on a full non linear model starting from voltages input able to determine its own attitude through an onboard sensor modeling to have a desired trajectory. The major goal of this ongoing research is the development and implementation of an autonomous flight control system for a quadrotor helicopter. Controlling a Vertical Taking-Off and Landing (VTOL) flying vehicle is basically dealing with highly unstable dynamics and strong axes coupling. The simulation results showed a satisfactorily performance of the proposed controllers adopted on the quadrotor in face off the presence of coupling and nonlinearties.
Vertical flight, hover, landing and horizontal flight are among the considered flight features in a predetermined trajectory.
