Linear stability analysis of systems with Preisach memory
We consider differential equations coupled with the input-output memory relation defined by the Preisach operator.
The differential equation relates an instant value of the rate of change of the output of the Preisach operator
with an instant value of its input. We propose an algorithm for the linearisation of the evolution operator of the system
and apply it to define the characteristic multiplier of periodic solutions, which determines their stability.
Examples of the system considered include models of terrestrial hydrology and electronic oscillators with hysteresis.
