Active suspension with multilayer dielectric elastomer actuator

摘要

A promising application for dielectric elastomer actuators (DEA) is the active vibration control in the low frequency range (0 - 200 Hz). The active and passive properties of the actuator can be joined to eliminate the disturbances in the whole frequency range. These actuators can be used for protection of lightweight sensible equipment like optic e. g. components. This paper describes the dynamic modeling of dielectric elastomer actuators (DEA) and the design of control algorithms for applications like active suspensions. The used least mean squares parametric estimation method for dynamic modeling of DEA shows a good accordance with the real system. Moreover, the developed feedback controller improves the isolation characteristics of passive dielectric elastomer.
