In this paper we develop an adaptive version of the so-called modified Prandtl-Ishlinskii model of hysteresis. This model is able to capture various shapes of hysteresis and, moreover, it admits an explicit mathematical formulation for the inverse model. The Lyapunov-based adaptation is then used to compensate the hysteretic nonlinearities of an unconventional actuator based on magnetic shape memory alloys.

Abstract
In this paper we develop an adaptive version of the so-called modified Prandtl-Ishlinskii model of hysteresis. This model is able to capture various shapes of hysteresis and, moreover, it admits an explicit mathematical formulation for the inverse model. The Lyapunov-based adaptation is then used to compensate the hysteretic nonlinearities of an unconventional actuator based on magnetic shape memory alloys.File in questo prodotto:
