Biography

Prof. Rogelio Lozano obtained his Ph.D. in Automatic Control at LAG-INPG, France, in 1981. He joined the Department of Electrical Engineering at CINVESTAV, Mexico, in 1981, where he worked until 1989, and has been Director of Research at CNRS since 1990.

Since April 2008, he has headed the UMI-LAFMIA at CINVESTAV in Mexico. His research interests include observers for nonlinear dynamical systems, passive systems, and modeling and adaptive control of unmanned aerial systems.

In 2008, he founded the International Joint Unit UMI-LAFMIA, supported by CONACYT, CNRS of France, and CINVESTAV. Later, together with Sergio Salazar Cruz, he created the SANAS master’s and doctoral programs in Autonomous Aerial and Underwater Navigation Systems.

His publications have an h-index of 50 in Scopus and nearly 11,000 citations.

Abstract

This talk presents the development of the dynamical model of a planar vertical take-off and landing (PVTOL) vehicle carrying a suspended load.

The complete model is obtained using the Euler–Lagrange approach. A nonlinear controller is then synthesized to stabilize the vehicle at a desired position while also stabilizing the load.

Stability is obtained using LaSalle’s invariance theorem, and the performance of the controller is shown through numerical simulations.
