A stabilized controllability of selemion CMV-based IPMC actuators in the extremely low humidity environment

Abstract

Selemion CMV-based IPMC (Ionic Polymer Metal Composite) actuators have numerous promising applications in designing autonomous moving structures. This paper presents the electric properties obtained from the analysis of circuit model of Selemion CMV-based IPMC. A circuit model had been proposed for deriving the time-dependent behavior of charge, which was caused by both Faradaic and non-Faradaic currents, passing through the IPMC. In the course of derivation, electrical properties of the IPMC were obtained and analyzed. It had been established that, the bending curvature of a Selemion CMV-based IPMC is basically proportional to the total charge imposed as a result of the applied voltage. This property is the basis of controllers for the Selemion CMV-based IPMC bending behavior. Bending curvature experiments were performed on Selemion CMV-based IPMCs, obtaining the actuator's dynamics and transfer function for controlling purposes of the Selemion CMV-based IPMC actuators in the extremely low humidity environment was computed and analyzed.
