Adaptive internal model regulation of a pvtol vehicle

Abstract We propose an adaptive control scheme to regulate the landing process of a PVTOL vehicle on an oscillating platform. In this approach we consider the oscillating reference as a sum of sinusoidal signals whose frequencies, phase and amplitude are all unknown. The suggested controller does not use velocity measurements and guarantee that the equilibrium point of the closed loop system is locally exponentially stable.
