Dynamic Modeling of Ionic Polymer Metal Composite Using Equivalent Passive Electric Network Components

Abstract

This paper presents dynamic modeling of Ionic Polymer Metal Composites (IPMC) using passive electric network components. The dynamic model using standard electric network components is a novel approach to model the transient and steady state voltage and current characteristics of IPMCs. This leads to a global model for IPMCs with fine tunable parameters, which depend on the material properties, the manufacturing process and the physical dimensions of the actuator. The dynamic model has been verified by simulation, system identification and experimental studies.
