System design for aluminum plate with peltier device using an operator-based observer

Abstract

In this paper, an operator-based robust nonlinear perfect tracking control for an aluminum plate with a peltier device in the presence of unknown uncertainties is proposed by an operator-based observer based on robust right coprime factorization approach. In general, there exist unknown uncertainties consisting of modeling errors and external disturbances in real situations. Considering the uncertainties, an operator-based robust nonlinear perfect tracking control using robust right coprime factorization is studied. That is, first, considering the unknown uncertain plant generates limitations in obtaining the so-called universal condition, an operator-based nonlinear feedback control scheme to eliminate the effect of uncertain plant is presented by an operator-based observer based on nominal plant. Second, a new perfect tracking condition to the designed control scheme is obtained. Finally, the effectiveness of the designed system is confirmed by simulation results.
