Transverse Feedback Control for Path Following with Quadrotors
This work presents a path following controller for a quadrotor vehicle. A smooth, dynamic, feedback controller is designed that allows the quadrotor to follow both closed and non-closed embedded curves while maintaining a desired speed, a desired acceleration or while stabilizing desired points along the curves. The nonlinear dynamic model of the quadrotor is transformed into a linear system via a coordinate and feedback linearization transformation. Once transformed, a path following controller is designed that guarantees invariance of the path while enforcing the desired motion along the path.
