About

Dafizal Derawi is a researcher specializing in the robust control and real-time attitude estimation of small-scale aerial robots, with a particular focus on hexarotor and multirotor vehicles. His most cited work, "Robust optimal attitude control of hexarotor robotic vehicles" (2013, 55 citations), addresses the critical challenge of stabilizing and maneuvering hexarotor platforms under uncertainty, contributing foundational methods for reliable autonomous flight. Derawi further advanced the field with his real-time implementation of a nonlinear complementary filter on the special orthogonal group SO(3) for attitude estimation. This work fuses raw accelerometer, magnetometer, and gyroscope data to deliver robust, drift-free orientation estimates, a key enabler for agile and precise aerial robotics. By bridging theoretical control design with practical sensor fusion, Derawi’s research has directly supported the development of more resilient and responsive unmanned aerial systems. His contributions are particularly valuable for students and engineers working on autonomous navigation, sensor integration, and flight control in GPS-denied or dynamically challenging environments.
