This paper presents a control law that can counter both random disturbance and inertia matrix perturbation in quadrotor attitude stabilization. The control law consists of an ordinary proportional-derivative control and a disturbance compensation. The disturbance compensation is designed by creating a virtual force that always attracts the quadrotor’s state variables back to the equilibrium point. Numerical simulations demonstrate that the control law can counter the effect of the disturbance and perturbation by reducing the upper bound of solution and reducing the vibration effectively.
