Resumen:
In this paper, a discrete time feedback strategy for the control of a
DC-DC buck power converter is presented. For the design of the
controller, a nonlinear control technique based on differential
algebraic methods is applied. The resulting controller produces an
input-output linear stable system. Two main aspects have to be
highlighted from the approach presented here: firstly, a nonlinear
discrete-time model for the buck power converter is used; and secondly,
an inductor current observer (estimator) with linear error dynamic is
implemented, eliminating the need for a series resistor.
