Paper Abstract

Ionic polymer metal composites is the proposing material for applications, since it has many attractive qualities that are durability, aquatic, miniature and light-weighted. Especially, IPMC has extraordinary advantages that are large displacement at low driving voltage(~3V), low power consumption and simple structure. However, slow time response prevents IPMC from various applications. Since IPMC is generally used in simply-supported configuration, which has same characteristic with a cantilever beam, IPMC has natural frequency and it oscillates extremely at natural frequency. We propose new open loop control method based on frequency response, which is combined with conventional DC input. This method is experimentally tested and compared with result by conventional input.
