Abstract

A control device (10) that controls an output voltage of a converter includes: a neural network (11) configured to generate a control signal for controlling a power supply block (30) based on a detection signal from an output stage of the power supply block (30) that supplies power to a load of the converter; a model generator (12) configured to generate a model of a nonlinear dynamic system by machine-learning from the detection signal; a model storage (13) configured to store the model generated by the model generator (12); and a model switch (14) configured to switch to a model, which is selected from models stored in the model storage (13) and is optimal for a latest detection signal, and provide the switched model to the neural network (11), wherein the neural network (11) generates the control signal based on a future output voltage predicted by using the model provided by the model switch (14).
