This paper proposes a novel predefined-time secondary control framework for an islanded DC microgrid to achieve the current sharing and voltage regulation within a tunable settling time. An integrated error, namely, a positive linear combination of current sharing error and DC bus voltage error is constructed and then used in the design of finite/fixed-time feedback loop. Using the integrated error, instead of the current error and the voltage error separately, a unified finite/fixed-time controller structure is proposed to save the computation resource. In addition, the framework enables us to provide rigorous theoretical analysis of the resulting system, which shows the upper bound of convergence time is dependent on both control and system parameters of DC microgrid and therefore is tunable by adjusting control parameters. Finally, simulation tests are carried out to demonstrate the effectiveness of the methods.

Dielectric elastomer actuators (DEAs) have been widely employed to drive various soft robots, due to their quiet fast muscle-like behavior. It is significant but challenging to model and control these soft actuators, due to their viscoelastic property, irregular geometry, complex structure, etc. In this paper, we propose a data-driven sparse identification method to discover the hidden governing equations of DEAs. These equations can help us interpret the nonlinear properties of DEAs. Due to their low computational cost, we can further use these equations to explore classic model-based control methods for real-time accurate control of viscoelastic DEAs. The experiments show that the proposed method can model the viscoelastic behavior of the DEAs with reasonable accuracy. A feedforward controller is finally developed to validate the effectiveness of the proposed method. It is expected that this modeling method can pave the way for accurate control of soft actuators/robots with structural and material nonlinearities.
