Abstract

This research aims to create a novel controller for micro/nano-systems (sensors and actuators) operating in ionic liquid media. To illustrate the capability of the proposed controller based on numerical simulation, the controller’s impacts on a nano-mirror immersed in ionic liquid media are analyzed. Based on the modified couple stress theory, a two-degree-of-freedom descriptive formulation is developed to more precisely investigate the size-dependent dynamic performance of nano-mirrors. Also, nano-mirror physics is extended by employing resistive fluid as a continuum substance ranging from light to dense. Utilizing the lattice Boltzmann method, the dynamic performance of the nano-mirror is studied. Considering numerical results, a new model-based self-adaptive controller is designed and added to the system. Furthermore, a classical controller is designed. Finally, the advantages of the proposed methodology are compared with the results of classical control methods employed in such systems, for which a numerical model of the system’s dynamic behavior is developed.
