Abstract

Inductive inference methods are applied to obtain approximate solutions to integer programming problems arising from the control of power electronic equipment. Divan demonstrated a novel power inverter circuit using a resonant link running at a fixed frequency. This circuit reduces waveform synthesis to specification of a binary sequence, which determines the state of the inverter’s switches, and results in a large 0-1 integer programming problem. DeMarco and Divan proposed to select an optimal sequence with respect to a linear cost function using a branch-and-bound method. We show that this is not an efficient approach for realistic problems and propose an alternate strategy using simulated annealing. We have incorporated machine learning to synthesize the control sequence in real-time. Results comparing the two methods and demonstrating on-line control synthesis are given.
