Optimal Design of Electromagnetically Actuated MEMS Cantilevers [PDF]
Sensors, 2018 In this paper we present the numerical and experimental results of a design optimization of electromagnetic cantilevers. In particular, a cost-effective technique of evolutionary computing enabling the simultaneous minimization of multiple criteria is applied. A set of optimal solutions are subsequently fabricated and measured. The designed cantilevers

Non‐linear adaptive control for electromagnetic actuators [PDF]
IET Control Theory & Applications, 2013 The authors study here the problem of adaptive ‘soft‐landing’ control for electromagnetic actuators. The soft landing requires accurate control of the actuator's moving element between two desired positions. They propose a non‐linear adaptive controller to solve the problem of robust trajectory tracking for the moving element, when considering model ...
