Abstract :
In this paper, a discrete time approach for the control of the buck converter is presented. This approach is based on the use of sample and hold circuits and of an analog circuit error amplifier. The error amplifier is designed by application of the H∞ norm to the system´s complementary sensitivity function, suggesting an alternative method to deal with robust control design.
