Internal model control for shape memory alloy actuators using fuzzy based Preisach model
journal contribution
posted on 2023-06-09, 07:13 authored by Kyoung Kwan Ahn, Bao Kha NguyenBao Kha NguyenThis paper investigates a possible application of Preisach model to control shape memory alloy (SMA) actuators using an internal model control strategy. The developed strategy consists in including the Preisach hysteresis model of SMA actuator and the inverse Preisach model within the control structure. In this work, an extrema input hystory and a fuzzy inference is utilized to replace the classical Preisach model. This allows to reduce a large amount of experimental parameters and computation time of the classical Preisach model. To demonstrate the effectiveness of the proposed controller in improving control performance and hysteresis compensation of SMA actuators, experimental results from real time control are presented.
