revise the following abstract with academic style，Dielectric elastomer actuators (DEAs) have been widely adopted for designing soft robots due to their intrinsic compliance, large deformation, and high energy density etc. Accompanied with the extraordinary performance, the dynamic response of DEAs is highly nonlinear due to the viscoelasticity of the materials, which makes the modeling of DEAs quite challenging. Most recent studies mainly focused on describing DEAs’ one-dimensional dynamic behavior, while little attention has been paid to the complex coupling effect existing in multiple degree-of-freedom (DOF) DEAs. In this paper, we proposed a general framework for handling the modeling and control problem of multiple DOF DEAs. Utilizing sparse regression, parsimonious governing equation describing the dynamic behavior of DEAs can be built from experimental measurement data. Based on the governing equation, model predictive controllers can be designed to satisfy various task specific requirements. The proposed control framework was verified with high precision tracking control on both 1 DOF and 2DOF DEAs. We believe the proposed method can greatly expand the modeling scope of current research, which can further lead to high precision control of a lot more complex soft robots.
