Poly-optimization of coil in electromagnetic linear actuator
2007The main advantages of the electromagnetic linear actuators are the simple design structure, the fast response for input signal, a possibility to achieve a high linear acceleration and a low cost of maintenance [4][5]. Moreover, a linear motion is a natural output, so there is no need of any mechanical transmission.

Modeling and feedback linearization based control of an electromagnetic clutch actuator
2014 IEEE Conference on Control Applications (CCA), 2014In automotive clutch applications the use of purely electromagnetic actuators is not yet very common. Their dynamics are nonlinear and often subject to kinematic constraints. Therefore their accurate control is a challenging task. In this paper, a plant model of an electromagnetic clutch actuator is developed from the corresponding physical principles.

Development of a pneumatic-electromagnetic hybrid linear actuator with an integrated structure
2015 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2015Conventional hybrid actuators can achieve a better force/torque bandwidth than a single principle actuator without losing back-drivability. However, hybrid actuators occupy space at least equal to the sum of the volumes of two or more actuators and multiple transmissions consisting of timing belts, gears, links, tendons, or Bowden-cables.

Self sensing: closed-loop estimation for a linear electromagnetic actuator
Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001Self-sensing is a valuable technique that allows information about position and/or force to be obtained directly from the actuator, without separate sensors. This technique has been applied to piezoceramic actuators and electromagnets for vibration control applications.

Optimization of an Electromagnetic Linear Actuator Operating in Error Actuated Control System
2008In the paper an algorithm and computer software for the optimisation of error actuated control systems containing of an electromagnetic linear actuator is presented. The software consists of two main parts: (a) optimisation solver and (b) numerical model of the actuator. For the optimisation, the genetic algorithm (GA) has been used. The field discrete
