A Spintronic Memristor Based PID Controller

Abstract

Abstract-The spintronic memristor was proposed based upon the magnetic theory shortly after the discovery of the Hewlett-Packard (HP) TiO2 memristor. Different from that of the TiO2 memristor, the resistance of a spintronic memristor not only depends on the historic profile of voltage and current through the device, but also is closely related to the current density. In this work, we review the mathematical model of the spintronic memristive device based on magnetic theory and analyze its memristive effects in detail. Then we provide a corresponding Simulink model. Furthermore, by incorporating the spintronic memristor into a conventional PID control circuit, the paper investigates an implementation approach for a novel compact memristive PID controller. The findings of the study may contribute to further development of the modern control technology, especially in hardware realization of micro-control system. Finally, reported simulations demonstrate the effectiveness of the proposed scheme.
