Abstract
We consider linear quadratic optimal control for a class of pulse-width-modulated systems. The problem is motivated from a practical application -- digital control of switching power converters. The control synthesis problem is posed based on a sampled data model of the original switching dynamics and a linear quadratic criterion that takes the inter sampling behavior into account.
