Optimal Design of Novel Electromagnetic-Ring Active Balancing Actuator with Radial Excitation

Design of natural frequency adjustable electromagnetic actuator and active vibration control test

An inertia electromagnetic actuator capable of adjusting natural frequency is designed in this paper. There are two procedures in the design of electromagnetic actuator: magnetic circuit design and stiffness conditioning design. ANSOFT software is used to simulate the magnetic circuit during the magnetic circuit design and optimize the design of the actuator. In order to adjust the natural freq...

The Optimal Design of a Concentric Coil, Radial Magnet Moving Magnet Actuator

Identification of an Electromagnetic Actuator

We apply time-domain system identification techniques to an electromagnetic actuator. This actuator is part of the vibration isolation testbed at the University of Michigan.

Optimal Actuator and Sensor Placement for Active Sensing

In active sensing, actuators are used to impart user-defined energy into a structure from which resulting sensor responses may be mined for useful information regarding the structure’s health. Optimal actuator-sensor placement works to maximize the observability of this information given two primary constraints: the number of actuators and sensors available for the network and the power availab...

Optimal Design of a Novel Permanent Magnetic Actuator using Evolutionary Strategy Algorithm and Kriging Meta-model

The novel permanent magnetic actuator (PMA) and its optimal design method were proposed in this paper. The proposed PMA is referred to as the separated permanent magnetic actuator (SPMA) and significantly superior in terms of its cost and performance level over a conventional PMA. The proposed optimal design method uses the evolutionary strategy algorithm (ESA), the kriging meta-model (KMM), an...
