| Research Abstract |
Ionic Polymer-Metal Composite (IPMC) is one of electroactive polymer actuators. It can be activated even by a ordinary dry cell battery. So, IPMC is a low energy consumption bending mode actuator. Control of its bending is a quite difficult task. Usually IPMC bending control is carried out merely by alternately changing polarity of voltage imposed on the IPMC according to the circumstances. It is a quite impractical way of bending control. In this study, we attempted to establish a controlling technique of IPMC bending based on the control theory. A transfer function of the IPMC was derived by FFT analysis. Employing the derived transfer function, we carried out bending control of IPMC by the methods of Feedforward, Feedback and Two-Degree-of-Freedom controls. It turned out that all three methods sufficiently well controlled the IPMC bending. Especially, Feedback and Two-Degree-of-Freedom controls made it possible to precisely control the IPMC bending.
