Identification and modeling of polymeric actuators: A comparison

In this paper different strategies to model Ionic Polymer-Polymer Composite (IP2C), used as actuator, are compared. Starting from some previous results regarding the ionic polymer metal composites (IPMCs) modeling, a linear gray-box model has been determined for an IP2C actuator. Moreover linear and nonlinear black-box models have been identified from experimental data. A comparison among developed models has been performed in order to determine the model that better describes the actuator behaviour.
