State-Robust Observability Measures for Sensor Selection in Nonlinear Dynamic Systems

no code implementations13 Jul 2023 Mohamad H. Kazma, Sebastian A. Nugroho, Aleksandar Haber, Ahmad F. Taha

The approach is performed by discretizing the system's dynamics using the implicit Runge-Kutta method and by introducing a state-averaged observability measure.

Data-driven Estimation, Tracking, and System Identification of Deterministic and Stochastic Optical Spot Dynamics

no code implementations29 Jan 2023 Aleksandar Haber, Michael Krainak

Stabilization, disturbance rejection, and control of optical beams and optical spots are ubiquitous problems that are crucial for the development of optical systems for ground and space telescopes, free-space optical communication terminals, precise beam steering systems, and other types of optical systems.

A novel method for adaptive control of deformable mirrors

no code implementations9 Mar 2022 Aleksandar Haber

Our approach combines a simple open-loop control method with a recursive least squares method for dynamically updating the DM model.

Dual-Update Data-Driven Control of Deformable Mirrors Using Walsh Basis Functions

no code implementations5 Nov 2021 Aleksandar Haber, Thomas Bifano

The developed method updates both the DM model and DM control actions that produce desired mirror surface shapes.

Joint Sensor Node Selection and State Estimation for Nonlinear Networks and Systems

no code implementations8 Jun 2020 Aleksandar Haber

State estimation and sensor selection problems for nonlinear networks and systems are ubiquitous problems that are important for the control, monitoring, analysis, and prediction of a large number of engineered and physical systems.

Steady-State Control and Machine Learning of Large-Scale Deformable Mirror Models

no code implementations18 Nov 2019 Aleksandar Haber

The estimated models reproduce the input-output behavior of Vector AutoRegressive with eXogenous (VARX) input models and can be used for the design of high-performance AO systems.
