Delay-Adaptive Control of Large Gas Engines for Increased Fuel- and Operation-Flexibility

A model-based, delay-adaptive approach to control the rotational speed of the crankshaft in a gas engine power generation system is presented to provide a robust solution for challenges regarding fuel flexibility and operation flexibility in volatile energy production environments, such as 0-100% Hydrogen and micro-grid applications. The control design procedure based on a nonlinear engine model with parametric uncertainties including unknown transport delays is presented, simulation results provide insights in the functionality and testcell measurements highlight the practical applicability.
