abstract

• In this paper, a bank of nonlinear controllers is proposed for boost dc-dc converters in cascade connection (well- known as optimizers). Each optimizer is stabilized at its maximum power point by using a feedback linearization technique plus a conventional proportional and derivative controller. The proof of the internal stability is given by taking into account an electrical representation of the internal dynamics. The innovative nature of the proposed methodology features an improvement of the transient state of the system with a minimal steady state error even though conventional maximum power point tracking algorithm (MPPT) is used. Co-simulation tests (MATLAB and PSIM) are carried out by considering partial shading conditions in order to evaluate the performance of the controllers for the boost dc-dc converters in distributed maximum power point tracking (DMPPT) applications. © 2018 IEEE.
