FPGA-based LQG controller and hardware-in-the-loop simulator implementation for nanomechanical systems
Vojtěch Mlynář, Johannes Berndorfer, Andreas Kugi +1
We present an open-source framework for real-time Linear Quadratic Gaussian (LQG) control and hardware-in-the-loop (HIL) simulation on the affordable Red Pitaya STEMlab FPGA platfo…
Identification and optimal control strategies for the transversal splitting of ultra--cold Bose gases
Nikolaus Würkner, Yevhenii Kuriatnikov, Karthikeyan Kumaran +5
Splitting a Bose--Einstein condensate (BEC) is a key operation in fundamental physics experiments and emerging quantum technologies, where precise preparation of well--defined init…
Feedback stabilization of a nanoparticle at the intensity minimum of an optical double-well potential
Vojtěch Mlynář, Salambô Dago, Jakob Rieser +5
In this work, we develop and analyze adaptive feedback control strategies to stabilize and confine a nanoparticle at the unstable intensity minimum of an optical double-well potent…
Optimal Sensing of Momentum Kicks with a Feedback-Controlled Nanomechanical Resonator
Kaspar Schmerling, Hajrudin Bešić, Andreas Kugi +2
External disturbances exciting a mechanical resonator can be exploited to gain information on the environment. Many of these interactions manifest as momentum kicks, such as the re…
