Experimental Flight Testing of an Adaptive Autopilot with Parameter Drift Mitigation

no code implementations20 Apr 2023 Yin Yong Chee, Parham Oveissi, Siyuan Shao, Joonghyun Lee, Juan A. Paredes, Dennis S. Bernstein, Ankit Goel

This paper modifies an adaptive multicopter autopilot to mitigate instabilities caused by adaptive parameter drift and presents simulation and experimental results to validate the modified autopilot.

Experimental Flight Testing of a Fault-Tolerant Adaptive Autopilot for Fixed-Wing Aircraft

no code implementations24 Oct 2022 Joonghyun Lee, John Spencer, Siyuan Shao, Juan Augusto Paredes, Dennis S. Bernstein, Ankit Goel

Next, the performance of the adaptive autopilot is examined under failure conditions by simulating a scenario where one of the control surfaces is assumed to be stuck at an unknown angle.

An Adaptive Digital Autopilot for Fixed-Wing Aircraft with Actuator Faults

no code implementations21 Oct 2021 Joonghyun Lee, John Spencer, Juan Augusto Paredes, Sai Ravela, Dennis S. Bernstein, Ankit Goel
