Abstract

The ionic polymer metal composite (IPMC) belongs to the category electroactive polymers (EAP), many potential applications for low-mass high-displacement actuators in biomedical and robotic systems have been shown. But identification of some physical parameters for nonlinear IPMC models is still a difficult issue. Moreover, hysteretic behavior exists in IPMCs and affects the performance of actuators, even makes the system with these actuators exhibit undesirable oscillations and instability. In this paper, a new nonlinear model of the IPMC with uncertainties and hysteresis is obtained. According to hysteresis and uncertainties for the proposed model, a nonlinear robust control using operator-based robust right coprime factorization is designed for the IPMC. The effectiveness of the proposed method is confirmed through simulation and experiment.
