Research on the PID Controllers Algorithm of the Quad Rotor
摘要
In particular affine nonlinear controllers designed using geometric nonlinear control methods, integral backstepping control and backstepping based nonlinear PID controllers have been designed for quad rotor aircraft. A nonlinear simulator was designed to help validate the flight dynamics, aerodynamics models, and controllers developed for quad rotor aircraft. The rotation and translation performance of different nonlinear controllers designed for quad rotor aircraft can be easily verified using simulators in various configurations and subject to interference.
