A Robust Suboptimal PD Servo Con- troller for an Oriented PV System

Abstract

In the paper a synthesis of robust, optimal PD servo controller
is presented. The control system under consideration can be applied
in oriented photovoltaic (PV) system. The cost function describes
both the energy consumption and settling time. The control plant is
described by a transfer function with interval coefficients. The ro-
bust controller is required to keep the value of cost function in assu-
med limits and the closed-loop control system should be aperiodic
for each value of uncertain parameter of the plant. To the construc-
tion of controller a geometric approach were applied. The results of
simulations show, that the proposed controller is able to meet all
requirements.
