Abstract

This paper presents the design of a robust PID controller for a four quadrant DC to AC switched mode inverter, using a buckboost DC to DC converter. The designed controller is intended to decrease the total harmonic distortion (THD) in the output voltage against sudden load changes. The proposed robust controller is based in a classical two degree of freedom approach. The controller performance was tested by computer simulations
