Abstract

<abstract abstract-type="author" id="ab0005"> <title id="sect0005">Abstract</title> <sec> <p id="sp0050">This study examines the problem of designing a high-gain proportional integral controller for minimum-phase linear systems with mismatched parameter uncertainties and matched perturbations. The proposed method can efficiently eliminate the matched disturbance when the control gain is high enough and uses the static output feedback control technique to stabilize the closed-loop system. By using the singular perturbation theory, the system states are finally constrained in a bounded region. Simulation results show the effectiveness of the proposed method.</p> </sec> </abstract>
