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…
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.…
A Machine Learning-Based Reference Governor for Nonlinear Systems With Application to Automotive Fuel Cells
Mostafaali Ayubirad, Hamid R. Ossareh
The prediction-based nonlinear reference governor (PRG) is an add-on algorithm to enforce constraints on pre-stabilized nonlinear systems by modifying, whenever necessary, the refe…
