LQ Optimal Control for Power Tracking Operation of Wind Turbines
Aaron Grapentin, Arnold Sterle, Jörg Raisch +1
In this paper, an approach for active power control of individual wind turbines is presented. State-of-the-art controllers typically employ separate control loops for torque and pi…
Max-Consensus Over Fading Wireless Channels
Fabio Molinari, Navneet Agrawal, Sławomir Stanczak +1
The topic of this paper is achieving finite-time max-consensus in a multi-agent system that communicates over a fading wireless channel and exploits its interference property. This…
Iterative learning control in prosumer-based microgrids with hierarchical control
Lia Strenge, Xiaohan Jing, Ruth Boersma +5
Power systems are subject to fundamental changes due to the increasing infeed of renewable energy sources. Taking the accompanying decentralization of power generation into account…
Overcoming Output Constraints in Iterative Learning Control Systems by Reference Adaptation
Michael Meindl, Fabio Molinari, Jörg Raisch +1
Iterative Learning Control (ILC) schemes can guarantee properties such as asymptotic stability and monotonic error convergence, but do not, in general, ensure adherence to output c…
Fallback Strategies in Operation Control of Microgrids with Communication Failures
Inga Löser, Ajay Kumar Sampathirao, Steffen Hofmann +1
This paper proposes a model predictive control (MPC)-based energy management system to address communication failures in an islanded microgrid (MG). The energy management system re…
Hierarchical Event-triggered Learning for Cyclically Excited Systems with Application to Wireless Sensor Networks
Jonas Beuchert, Friedrich Solowjow, Jörg Raisch +2
Communication load is a limiting factor in many real-time systems. Event-triggered state estimation and event-triggered learning methods reduce network communication by sending inf…
