Multiphysics Modeling of Voice Coil Actuators With Recurrent Neural Network [PDF]
IEEE Journal on Multiscale and Multiphysics Computational Techniques, 2019 In order to accurately model the behaviors of a voice coil actuator (VCA), the three-dimensional (3-D) method is preferred over a lumped model. However, building a 3-D model of a VCA is often very computationally expensive. The computation efficiency can be limited by the spatial discretization, the multiphysics nature, and the nonlinearities of the ...
