Temperature Estimation of Electric Motors of Electric Actuators
SAE Technical Paper Series, 2022<div class="section abstract"><div class="htmlview paragraph">In the development of electric actuators, the electric motor to drive the actuator is quite often selected from a set of available motors that have been previously used on other similar programs, or based on legacy experience, or from those that are commercially available seeming

Compensation of backlash effects in an electrical actuator
2003 European Control Conference (ECC), 2003We develop for systems with backlash a non linear observer, based on the estimation of the disturbed torque transmitted due the dead zone. Then we design an adaptive controller using this non linear observer in order to compensate the disturbed torque on line. Simulation and experimantal results applied on an elecrical actuator are given to support the

Dynamics of an electrically actuated resonant microsensor
Proceedings International Conference on MEMS, NANO and Smart Systems, 2004We present a nonlinear model of an electrically actuated microbeam-based resonant microsensor encompassing the electrostatic force of an air gap capacitor, the restoring force of the microbeam, and the axial load applied to the microbeam. The model accounts for moderately large deflections, dynamic loads, and the coupling between the mechanical and ...

Regenerative amplification in a microtoroid by electrical actuation
2011 International Quantum Electronics Conference (IQEC) and Conference on Lasers and Electro-Optics (CLEO) Pacific Rim incorporating the Australasian Conference on Optics, Lasers and Spectroscopy and the Australian Conference on Optical Fibre Technology, 2011We investigate mechanical regenerative amplification in a microtoroid by electrical actuation, and compare the linewidths achievable to that found with optical driving. We find an order of magnitude lower linewidth by this method.

Smart Materials and Structures, 2009
This paper studies the nonlinear vibration of a clamped–clamped microresonator under combined electric and piezoelectric actuations. The electric actuation is induced by applying an AC–DC voltage between the microbeam and the electrode plate that lies on opposite sides of the microbeam, and the piezoelectric actuation is induced by applying the DC ...

Flow Control with Electric Actuators
HVAC&R Research, 1997High levels of measurement noise, nonlinear behavior, and conflicting performance requirements pose challenging problems for flow controllers in heating, ventilating, and air-conditioning (HVAC) systems. In this paper, a strategy is developed which is based on an analysis of the maximum system gain and an estimate of the variance of the noise.

Trends in developing electrical actuators
European Transactions on Electrical Power, 1992AbstractElectrical actuators are equipments for the conversion of electrical energy and signals into mechanical forces and movements. Sensors ‐ used in connection with these actuators ‐ are devices for the conversion of electromagnetic or mechanical units into electromagnetic signals.
