Multi-UAV systems · Bearing-only formation control · State estimation on S²
My research focuses on cooperative control of multi-UAV systems using only bearing measurements — no GPS, no distance sensors. Using robust nonlinear control techniques, I design formation controllers and state estimators that operate directly on the unit sphere S², enabling scalable drone swarms for GPS-denied environments.
Education
- Focus: Bearing-only formation control strategies for quad-rotor systems, contributing to advancements in multi-agent coordination.
- Designed and analyzed novel distributed control algorithms to enhance the autonomy and robustness of UAV swarms.
- Developed high-fidelity simulations in MATLAB and Python to validate theoretical control models and algorithm performance.
- Engineered a custom experimental platform with ROS 2, Gazebo Ionic, and an ESP32-Drone for hardware-in-the-loop (HIL) validation of control strategies.
- Conducted real multi-quadrotor flight experiments to validate the bearing-only controllers and estimators in hardware; a journal article with these results is in preparation.
- Funded by SECIHTI (Secretaría de Ciencia, Humanidades, Tecnología e Innovación).
- Thesis: Designed formation controllers for Quad-Rotor-type multi-agent systems, achieving precise control and coordination among multiple drones.
- Developed and tuned controllers for multiple aerial mobile nano-robots, optimizing performance and behavior across a range of operating scenarios.
- Built a ROS-based platform enabling coordination and communication among multiple vehicles for research and development.
- Set up Git repositories for version control, ensuring efficient collaboration and code management throughout the project.
- Funded by CONACYT (Consejo Nacional de Ciencia y Tecnología, now SECIHTI).
- Professional internship (dic. 2020 – jun. 2021): developed the control subsystem for a two-degree-of-freedom cooperating table for an arc welding robot, optimizing motion trajectories and coordination with the robot.
- Designed, assembled, and integrated the control cabinet; programmed the cooperative table positioning control system and implemented communication protocols with a Fanuc ARC Mate 100iC welding robot.
