Harmonic Stability of Power Systems: A Control-Theoretic Definition and Assessment Criteria
N. Bhoir, A. Sarkar, J. E. Machado +1
Harmonic interactions have become a defining dynamic stability phenomenon in converter-based power systems (CBPSs). However, a formalization of the notion of harmonic stability in…
Delay-Robust Primal-Dual Dynamics for Distributed Optimization
Gökçen Devlet Şen, Juan E. Machado, Gülay Öke Günel +1
Continuous-time primal-dual gradient dynamics (PDGD) is an ubiquitous approach for dynamically solving constrained distributed optimization problems. Yet, the distributed nature of…
Distributed Adaptive Control for DC Power Distribution in Hybrid-Electric Aircraft: Design and Experimental Validation
Wasif H. Syed, Juan E. Machado, Hans Würfel +2
To reduce CO2 emissions and tackle increasing fuel costs, the aviation industry is swiftly moving towards the electrification of aircraft. From the viewpoint of systems and control…
A Primal-Dual-Based Active Fault-Tolerant Control Scheme for Cyber-Physical Systems: Application to DC Microgrids
Wasif H. Syed, Juan E. Machado, Johannes Schiffer
We consider the problem of active fault-tolerant control in cyber-physical systems composed of strictly passive linear-time invariant dynamic subsystems. We cast the problem as a c…
An Input-Output Data-Driven Dissipativity Approach for Compositional Stability Certification of Interconnected LTI MIMO Systems
Alejandra Sandoval-Carranza, Juan E. Machado, Johannes Schiffer
We propose an input-output data-driven framework for certifying the stability of interconnected multiple-input-multiple-output linear time-invariant discrete-time systems via QSR-d…
Model Predictive Control of District Heating Grids Using Stabilizing Terminal Ingredients
Max Rose, Hannes Gernandt, Juan E. Machado +1
The transformation of fossil fuel-based district heating grids (DHGs) to CO-neutral DHGs requires the development of novel operating strategies. Model predictive control (MPC)…
