Thdi qualitative method for tuning of non-linear SFL and PBC controllers applied to boost PFC converter

In literature it is known that the tuning of nonlinear controllers is different from the classic control approach, since it is not given directly, because of the Laplace transform term. In this sense, the main goal of this work is to deduce intuitive method to obtain the nonlinear controllers gains for SFL and PBC applied to the PFC boost converter, a subject little discussed in nonlinear control background. These two methods are taken together due to the similarities in the equations.
