System-Level Modelling and Simulation of a Multiphysical Kick and Catch Actuator System

Abstract: This paper presents a system-level model of a microsystem architecture deploying cooperating microactuators. An assembly of a piezoelectric kick-actuator and an electromagnetic catch-actuator manipulates a structurally unconnected, magnetized micromirror. The absence of mechanical connections allows for large deflections and multistability. Closed-loop feedback control allows this setup to achieve high accuracy, but requires fast and precise system-level models of each component. Such models can be generated d… Show more

“…Scognamillo et al [21] exercised a MOR code, FANTASTIC, to evaluate the nonlinear thermal activities of a coupled electrothermal PEM model. A multiphysical ROM of a piezoelectric actuator considering nonlinear inputs was achieved, through Krylov subspace-based MOR method, by Sch¨ utz et al [22]. In a recent investigation [23], the temperature-dependent coefficient of thermal expansion (CTE) of the wire material of a PEM has been parametrised in direct coupled thermal-mechanical parametric reduced order modelling.…”
