Multirotor unmanned aerial vehicle attitude and altitude control

Nowadays unmanned aerial vehicles are being used surveilance, search and rescue, damage assesment alongwith areas where dangereous for people to work. In this work an unmanned multirotor aerial vehicle will be designed. Altitude control and position control of the vehicle will be handled . Mostly focused quarotor control in the work. Multirotor unmanned aerial vehicles have 6 degrees of freedom. Complementary Filter will be used inorder to eliminating disturbances and for state estimation. Inertial Measurement Unit will be composed for flight stability. Quadrotor?s altitude, speed, direction datas will be chased and evaluated by the Inertial Measurement Unit. There will be a central microcontroller which will manage all the components that necessary for flight. The microcontroller will use the data coming from Inertial Measurement Unit and user inorder to control motor speed. While all the design criterias are being considered, we paid attention to be quadrotor light, stable flight, fast maneuver. The principal components used are brusless DC motors for rotors, accelerometer and gyroscope for Inertial Measurement Unit, remote controller for remote control and microcontroller which has 16 analog to digital converter and 15 PWM output.
