Prandtl-Ishlinskii hysteresis models for complex time dependent hysteresis nonlinearities

We introduce a new class of time dependent hysteresis models by combining the time dependent Prandtl-Ishlinskii model with functional nonlinearities. This combination improves the capability of the time dependent Prandtl-Ishlinskii model to characterize a class of complex time dependent hysteresis nonlinearities in smart actuators. The analytical inversion for the proposed time dependent hysteresis model is also presented in order to extend the inversion algorithm of the inverse time dependent Prandtl-Ishlinskii model for a class of complex time dependent hysteresis nonlinearities.
