Delay-Robust Primal-Dual Dynamics for Distributed Optimization
Gökçen Devlet Åen, Juan E. Machado, Gülay Ãke 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…
Interturn Fault Detection in IPMSMs: Two Adaptive Observer-based Solutions
Romeo Ortega, Alexey Bobtsov, Leyan Fang +2
In this paper we address the problem of online detection of inter-turn short-circuit faults (ITSCFs) that occur in permanent magnet synchronous motors (PMSMs). We propose two solut…
