Electrostatic Circular Membrane MEMS: An Approach to the Optimal Control

Computation, 2021
The recovery of the membrane profile of an electrostatic micro-electro-mechanical system (MEMS) is an important issue, because, when an external electrical voltage is applied, the membrane deforms with the risk of touching the upper plate of the device ...
