Adaptive altitude control for a small helicopter in a vertical flying stand

In this paper, we focus on the design and implementation of a controller for a two degree-of-freedom system. This system is composed of a small-scale helicopter which is mounted on a vertical platform. The model is based on Lagrangian formulation and the controller is obtained by classical pole-placement techniques for the yaw dynamics and adaptive pole-placement for the altitude dynamics. Experimental results show the performance of such a controller.
