...Da Huo; Carrie M. Hall This study presents a novel approach to optimal control utilizing a Koopman operator integrated with a linear quadratic regulator (LQR) to enhance the thermal management and power output efficiency of an open-cathode proton exchange membrane fuel cell (PEMFC) stack. First...

... of convexification for the underlying receding-horizon constrained optimization problem: the Koopman-operator lifting and the McCormick envelopes implemented for handling the bilinear dynamics. The proposed control method is evaluated with simulation study, by developing a Modelica-Python cosimulation platform via...

... nonlinear dynamic modeling framework based on the Koopman operator and DMD, as well as the basic formulation of SINDYc-based model identification by use of historical operation data, followed by the derivation of the static input–output models. In Sec. 3 , the problem formulation for the constrained SOC...
