Analysis of memristor based model reference adaptive controller (MRACs)

In this paper, for the first time, we propose an adaptive controller based on a new electrical element “Memristor” which will not only improve the system stability and performance, but also maintain that stability for a longer time, irrespective of different perturbation factors. Memristor changes its resistance on changing voltage or current through it which makes our proposed stability controller more flexible during runtime, compared to traditional stability controller. To illustrate this, a highly unstable plant is taken as an example which demands continuous stability for a long duration. The output results are demonstrated by simulation results and are verified by mathematical reasoning to support the unusual and unexpected characteristics.
