Optimal Design of Electromagnetically Actuated MEMS Cantilevers [PDF]

open access: yesSensors, 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

Sensor-less parameter estimation of electromagnetic actuator for shunt damping

open access: yesNihon Kikai Gakkai ronbunshu, 2015
Electromagnetic shunt damping is a sensor-less passive damping technique using an electromagnetic actuator. The accurate values of the parameters of the system are essentially required for designing a controller in the damping technique.

Real-Time Electromagnetic Estimation for Reluctance Actuators [PDF]

open access: yesIEEE Transactions on Industrial Electronics, 2019
Several modeling, estimation, and control strategies have been recently presented for simple reluctance devices like solenoid valves and electromagnetic switches. In this paper, we present a new algorithm to online estimate the flux linkage and the electrical time-variant parameters of these devices, namely the resistance and the inductance, only by ...

The Emvibe: An Electromagnetically Actuated Vibraphone

open access: yes, 2012
The EMvibe is an augmented vibraphone that allows for continuous control over the amplitude and spectrum of in-dividual notes. The system uses electromagnetic actuators to induce vibrations in the vibraphone's aluminum tone bars. The tone bars and the electromagnetic actuators are coupled via neodymium magnets affixed to each bar.
