Design of adaptive I-PD control system with variable reference model

Abstract

As one of the control schemes which overcome model uncertainty, there is a model reference adaptive control. In the conventional adaptive control method, the reference model is designed in advance. However, this reference model should also be essentially re-designed according to characteristic change of a controlled object. Therefore, in this paper, we propose an adaptive I-PD control scheme with variable reference model and show the validity by the numeric simulation.
