Frequency-Based Wind Gust Estimation for Quadrotors Using a Nonlinear Disturbance Observer

RA-L 2022

In city-wide weather prediction, wind gust information can be obtained using unmanned aerial vehicles (UAVs). Although wind sensors are available, an algorithm-based active estimation can be helpful not only as a weightless substitute but also as feedback for robust control. This paper aims to estim

Safe high impedance control of a series-elastic actuator with a disturbance observer

ICRA 2020poster

In many series-elastic actuator applications, the ability to safely render a wide range of impedance is important. Advanced torque control techniques such as the disturbance observer (DOB) can improve torque tracking performance, but their impact on safe impedance range is not established. Here, saf…
