VSCL Presents System Identification Project Update at Center for Autonomous Air Mobility and Sensing (CAAMS) Summer Meeting

Posted on by

In conjunction with Dr. Moble Benedict (AVFL Lab – TAMU), Dr Puneet Singla (CASS Lab – Penn State), and Dr. Randy Beard (MAGICC Lab – BYU), Dr. Valasek presented the current updates of the System Identification project at the National Science Foundation (NSF) CAAMS Summer Industry Advisory Board Meeting.

The project “Integration of System Theory with Machine Learning Tools for Data Driven System Identification” integrates system theory with machine learning tools for data driven system identification. The objective is to derive nonlinear dynamical models by employing a unique handshake between linear time varying subspace methods and sparse approximation tools from high fidelity flight simulations and flight experiments.

The center is a partnership between academia, industry, and government to offer pre-competitive research in autonomous air mobility and sensing.

Valasek Receives Teaching Impact Award and Engineering Genesis for Multidisciplinary Research

Posted on by

Dr. John Valasek received two distinguishing awards during the Spring 2024 semester. In the Faculty Excellence Awards category, Valasek was awarded the College of Engineering Teaching Impact Award. This award recognizes individuals who have had a profound impact on students through their teaching. Valasek received the award for the career achievements of his former graduate and undergraduate students.

Valasek was also awarded the Engineering Genesis Award for Multidisciplinary Research. This award was created to honor Texas A&M Engineering Experiment Station (TEES) researchers who have secured a grant of $1 million or more for a research project. Valasek is the PI for the project: “Enhancing the Cycle-of-Learning for Autonomous Systems to Facilitate Human-Agent Teaming”.

MD Sunbeam Defends Masters Thesis

Posted on by

MD Sunbeam (B.S. Aerospace Engineering, University of Texas) successfully defended his Masters thesis: “Gaze-Regularized Imitation Learning”. 

Approaches for teaching learning agents via human demonstrations have been widely studied and successfully applied to multiple domains. However, the majority of imitation learning work utilizes only behavioral information from the demonstrator, i.e. which actions were taken, and ignores other useful information. In particular, eye gaze information can give valuable insight towards where the demonstrator is allocating visual attention, and holds the potential to improve agent performance and generalization. In this work, we propose Gaze Regularized Imitation Learning (GRIL), a novel context-aware, imitation learning architecture that learns concurrently from both human demonstrations and eye gaze to solve tasks where visual attention provides important context. We apply GRIL to a visual navigation task, in which an unmanned quadrotor is trained to search for and navigate to a target vehicle in a photo-realistic simulated environment. We show that GRIL outperforms several state-of-the-art gaze-based imitation learning algorithms, simultaneously learns to predict human visual attention, and generalizes to scenarios not present in the training data.

This work is sponsored by the Army Research Laboratory (ARL) through the Cycle of Learning Project. MD Sunbeam is employed as a researcher at the Human Research and Engineering Directorate (HRED), ARL.

Cassie-Kay McQuinn Defends Masters Thesis

Posted on by

Cassie-Kay McQuinn (B.S. Aerospace Engineering, TAMU) successfully defended her Masters thesis titled “Online Near-Real Time Open-Loop System Identification from Closed-Loop Flight Test Data“.

Cassie-Kay’s thesis investigated identifying linear dynamic models onboard a vehicle in near-real time with and without an active controller. This is performed for a small Unmanned Air System (UAS) utilizing low cost, commercial-off-the-shelf components. Bare airframe longitudinal, lateral/directional and combined longitudinal lateral/directional models of the test vehicle are generated both onboard the vehicle during flight and offline during post-processing. The Developmental Flight Test Instrumentation 2 (DFTI2), utilizing the Robot Operating System (ROS), is extended to compute system models onboard the vehicle from both open-loop and closed-loop data. Additionally, a controller is implemented into the system, external to the primary flight controller, to generate and record controller inputs for the closed-loop system. The Observer/Kalman filter Identification (OKID) algorithm is used to generate locally linear models of the flight vehicle. Models are generated independent of actuator dynamics by mapping deflection angle to measured servo potentiometer readings. Orthogonal Schroeder sine sweep excitations are utilized to reduce potential control coupling while also exciting multiple frequencies. Identified models are presented and evaluated. Offline analysis of closed-loop flight data provides insight into the controller utilized in flight. Results presented in the thesis show the extended system can generate models suitable for describing the dynamics of the vehicle operating both with and without a controller implemented.

This work is sponsored by the National Science Foundation (NSF)  Center for Autonomous Air Mobility and Sensing (CAAMS). Conference and journal papers are being written on this work. Cassie-Kay’s is the 60th graduate degree earned by a VSCL graduate student.
