Abstract

In this paper, a Koopman based control technique is presented for voltage regulation of a boost converter feeding a constant power load (CPL). The nonlinearity of the boost converter and CPL can make the system unstable, with closed loop stability typically ensured only locally. To address these challenges, a data-driven Koopman operator approximation is developed for output voltage regulation using Koopman based model predictive control (KMPC). The tracking performance is demonstrated when the system is subject to changes in voltage reference and load power. Closed-loop simulation results are shown offline using Matlab/Simulink, and in real time using Opal RT. The KMPC problem is solved using mpcqpsolver, which allows for code generation and real time simulation, to demonstrate feasibility of online implementation of the controller.
