The main objective of this research study is the control of a DC-AC full-bridge buck-based inverter through an extension of Model reference adaptive control (MRAC) strategy, in particular the Extended Minimal Controller Synthesis. This approach requires minimal knowledge of plant and disturbance parameters offering a good robustness even in presence of parameters variation, plant unmodeled nonlinearities and external disturbances. The rejection of undesirable effects of sudden load changes and the ability to recover regular operation with a low transient error, in a short number of periods and the high robustness guarantee that high performance is kept when the control signal is injected through a PWM generator switching at realistic frequency.
