Experimental Flight Testing of a Fault-Tolerant Adaptive Autopilot for Fixed-Wing Aircraft
Joonghyun Lee, John Spencer, Siyuan Shao +3
This paper presents an adaptive autopilot for fixed-wing aircraft and compares its performance with a fixed-gain autopilot. The adaptive autopilot is constructed by augmenting the…
An Adaptive Digital Autopilot for Fixed-Wing Aircraft with Actuator Faults
Joonghyun Lee, John Spencer, Juan Augusto Paredes +3
This paper develops an adaptive digital autopilot for a fixed-wing aircraft and compares its performance with a fixed-gain autopilot. The adaptive digital autopilot is constructed…
An Adaptive PID Autotuner for Multicopters with Experimental Results
John Spencer, Joonghyun Lee, Juan Augusto Paredes +2
This paper develops an adaptive PID autotuner for multicopters, and presents simulation and experimental results. The autotuner consists of adaptive digital control laws based on r…
Self-Excited Dynamics of Discrete-Time Lur'e Systems
Juan A. Paredes, Syed Aseem Ul Islam, Omran Kouba +1
Self-excited systems arise in numerous applications, such as biochemical systems, fluid-structure interaction, and combustion. This paper analyzes a discrete-time Lur'e system with…
Regularization-Induced Bias and Consistency in Recursive Least Squares
Brian Lai, Syed Aseem Ul Islam, Dennis S. Bernstein
Within the context of recursive least squares (RLS) parameter estimation, the goal of the present paper is to study the effect of regularization-induced bias on the transient and a…
Two Modifications of the Unscented Kalman Filter that Specialize to the Kalman Filter for Linear Systems
Ankit Goel, Dennis S. Bernstein
Although the unscented Kalman filter (UKF) is applicable to nonlinear systems, it turns out that, for linear systems, UKF does not specialize to the classical Kalman filter. This s…
