Power-Duration Characterization of Aggregated Thermostatically Controlled Loads via Reach and Hold Sets
Mazen Elsaadany, Hamid R. Ossareh, Mads R. Almassalkhi
Aggregations of thermostatically controlled loads (TCLs), such as air conditioners, offer valuable flexibility to the power grid. The aggregate power consumption of a TCL fleet can…
Comprehensive Dynamic Modeling and Constraint-Aware Air Supply Control for Localized Water Management in Automotive Polymer Electrolyte Membrane Fuel Cells
Mostafaali Ayubirad, Zeng Qiu, Hao Wang +3
In this paper, a predictive constraint-aware control scheme is formulated within the Command Governor (CG) framework for localized hydration management of a proton exchange membran…
Improved Voltage Regulation with Optimal Design of Decentralized Volt-VAr Control
Daniel Russell, Dakota Hamilton, Mads R. Almassalkhi +1
Integration of distributed energy resources has created a need for autonomous, dynamic voltage regulation. Decentralized Volt-VAr Control (VVC) of grid-connected inverters presents…
Hierarchical Fuel-Cell Airpath Control: an Efficiency-Aware MIMO Control Approach Combined with a Novel Constraint-Enforcing Reference Governor
Eli Bacher-Chong, Mostafa Ali Ayubirad, Zeng Qiu +3
This paper presents a hierarchical multivariable control and constraint management approach for an air supply system for a proton exchange membrane fuel cell (PEMFC) system. The co…
A Neural Network-based Multi-timestep Command Governor for Nonlinear Systems with Constraints
Mostafaali Ayubirad, Hamid R. Ossareh
The multi-timestep command governor (MCG) is an add-on algorithm that enforces constraints by modifying, at each timestep, the reference command to a pre-stabilized control system.…
CPU- and GPU-Based Parallelization of the Robust Reference Governor
Hamid R. Ossareh, William Shayne, Samuel Chevalier
Constraint management is a central challenge in modern control systems. A solution is the Reference Governor (RG), which is an add-on strategy to pre-stabilized feedback control sy…
