The Yakubovich–Kalman–Popov Lemma and Stability Analysis of Dynamic Output Feedback Systems

International Journal of Robust and Nonlinear Control, 2006
This paper presents theory related to stability analysis and stability criteria relevant for observer-based feedback control systems. To this purpose, a special formulation of the Yakubovich-Kalman-Popov (YKP) lemma is provided.

Stability Results of Popov-Type for Infinite-Dimensional Systems With Applications to Integral Control

Proceedings of the London Mathematical Society, 2003
We derive absolute stability results of Popov-type for infinite-dimensional systems in an input-output setting. Our results apply to feedback systems where the linear part is the series interconnection of an L2-stable linear system and an integrator, and

Direct Recycling of Mixed-Oxide Cathodes: Balancing Cost, Performance and Environmental Trade-Offs. [PDF]

Adv Sci (Weinh)
Direct regeneration routes for mixed‐oxide lithium‐ion battery cathodes are systematically compared using harmonized techno‐economic, electrochemical, and environmental metrics. Solid‐state, hydrothermal, molten salt, electrochemical, and chemical relithiation methods are benchmarked to identify performance, cost, and sustainability trade‐offs.

On input-to-state stability of stochastic retarded systems with Markovian switching [PDF]

, 2009
This note develops a Razumikhin-type theorem on pth moment input-to-state stability of hybrid stochastic retarded systems (also known as stochastic retarded systems with Markovian switching), which is an improvement of an existing result.

Time Delay Compensation and Stability Analysis of Networked Predictive Control Systems Based on Hammerstein Model [PDF]

, 2007
A novel approach is proposed for a networked control system with random delays containing a nonlinear process based on a Hammerstein model. The method uses a time delay two step generalized predictive control (TDTSGPC), which consists of two parts, one ...

Stability analysis of adaptive output feedback control

, 1999
This paper presents stability theory of adaptive systems using an extension of the Yakubovich-Kalman-Popov (YKP) lemma. Such stability analysis is relevant for observer-based adaptive feedback control systems.

Robust stability of non linear time varying systems [PDF]

, 1999
summary:Systems with time-varying non-linearity confined to a given sector (Luré type) and a linear part with uncertainty formulated by an interval transfer function, are considered.

Towards data‐driven predictive maintenance for vacuum ion pumps at European XFEL

Journal of Synchrotron Radiation, EarlyView.
This paper presents a machine‐learning‐based approach for early fault detection in vacuum ion pumps at the European XFEL by analyzing pressure data to detect fault precursors. The developed method enables predictive maintenance, reducing unplanned downtime and improving operational reliability.Large‐scale scientific facilities, such as the European ...
