Research Project Spotlight

Project: System Identification for Unmanned Air Systems

Sponsor: National Science Foundation (NSF) Center for Autonomous Air Mobility & Sensing (CAAMS)

Purpose: System Identification is a process to develop a mathematical representation of the dynamics of a physical system from measured data. Accurate models enable prediction of performance and dynamics of a system.

Challenges: Models for sUAS are generally not available as manufacturers do not have models for commercial sUAS and models for military sUAS are not typically available. Modeling and control systems are often vehicle dependent and not easily portable across sUAS. Many commercial autopilots do not provide data needed for online system identification

Our Approach: Utilizing the Observer Kalman Filter Identification algorithm with the Developmental Flight Test Instrumentation 2 framework, full state space models can be identified in near-real time onboard the vehicle utilizing data from a variety of sensors.

Payton Clem Defends Masters Thesis

Posted on by

Payton Clem successfully defended her M.S. thesis Autonomous Target Tracking of Hostile Ground Target under Wind Disturbance and Sun Concealment using Deep Reinforcement Learning on 12 December.  Payton has been with VSCL since the first semester of her senior year and is highly engaged in AI and flight testing.

Intelligence, surveillance, and reconnaissance (ISR) missions benefit from the use of unmanned aircraft systems (UAS) capable of maintaining visual contact with ground targets, referred to here as target tracking. For practical deployment, it is valuable for tracking to be autonomous and function without detailed knowledge of the surrounding environment. The task becomes more complex when additional objectives, such as concealment or avoiding a hostile target, are introduced. To address this problem, a Soft Actor-Critic (SAC) reinforcement learning controller is developed that uses only the target’s location in the image frame. The agent controls a multirotor UAS equipped with a fixed optical sensor, requiring the agent to adjust vehicle attitude to keep the target in view while accounting for wind, varying target behaviors, altitude-based concealment constraints, and sun-related concealment. Previous work on fixed-camera target tracking has shown that RL-based algorithms can produce unstable behaviors such as control oscillations and large altitude changes. This work focuses on reward shaping to mitigate these issues and encourage stable, consistent tracking. In addition, the influence of including solar concealment information in the reward function is examined to assess its effect on vehicle behavior. The results demonstrate that the proposed reward structure effectively reduces unwanted behaviors such as diving and pitch and yaw ringing. The reward structure enables stable, long-duration tracking, despite the incorporation of constraints associated with sun concealment strategies. The resulting policy achieves reliable tracking across the evaluated conditions.

Payton’s research is supported by the Army Research Laboratory on the project Robust Threat Detection for Ground Combat Vehicles with Multi-Domain Surveillance in Hostile Environments

1st Lt Noah R. Luna defends Masters Thesis

Posted on by

1st Lt Noah R. Luna, USAF successfully defended his M.S. thesis on June 12th, 2025.  Noah has been with VSCL since he graduated from the USAF Academy and commissioned in June 2023.  The title of his thesis is: Real-Time Controller Architecture for the Flight Test of Custom Control Algorithms on Small Unmanned Aircraft Systems

Flight test of experimental controller designs can be difficult when using commercially available hardware on small unmanned aircraft systems. The supported software often relies on specific messaging protocols to send commands to the aircraft which can vary significantly between controllers. Furthermore, modification of an existing package to accept different types of controllers can prove to be a difficult task. This thesis details a real-time control architecture for small unmanned aircraft systems, named Kanan, capable of safely and quickly integrating a variety of flight controller designs on a various platforms including fixed-wing aircraft and rotorcraft. Kanan is a C++ based software package which supports command authority using RC channel overrides, attitude control, and both local and global position control. The Robot Operating System and MAVLink messaging protocols are fundamental for how messages are shared between an Ardupilot flight stack and onboard companion computer. Additionally, the framework provides support for pilot operated safety measures and the ability to perform common flight test maneuvers, such as doublets or sawtooth climbs, for further control system and vehicle analysis. A low-barrier to entry is achieved by restricting all necessary changes needed for various tests to only two files and including a graphical user interface to reduce the required experience to operate the ground station computer. Testing and development of experimental flight controllers with Kanan can be done more quickly and significant changes can be made to the control design without having to modify or sacrifice existing data logging and safety functionality.

Noah addressed the need for a capability to easily port custom complex control laws from our research into commercial autopilots for use in demonstrating and evaluating them in flight testing.  Noah has named his system Kanan, after his son Kanan whom was born a few short months ago. Noah’s research is supported by the United States Air Force and during his time with VSCL has contributed to all of the current research projects. Noah was also a grad assistant and lead for Dr. Valasek’s AERO 401/402 project this past year, in which a team of six Aero students addressed another need: a modular and extensible common architecture for sensors/avionics/navigation/autopilot. The new system is called Modular Open System Architecture for Low-cost Integrated Avionics (MOSA LINA).  A paper on this framework was submitted to 2026 AIAA SciTech.

Noah’s is the 65th graduate degree completed that Dr. John Valasek has advised.
