Abstract :
This work is devoted to the design of a sliding feedback control scheme for a buck converter in AC signal generation task where amplitude, frequency and offset can be externally adjusted. A sliding control law over an autonomous switching surface is proposed. As a result, the control scheme is found to be robust with respect to parameter variations and external disturbances. Simulations validating the design and some considerations on the control law implementation are also presented
