APPARATUS, CONTROLLER AND METHOD FOR ADAPTIVE CONTROL OF AN ELECTROMAGNETIC ACTUATOR |
摘要 |
Provided are a structure testing apparatus, a controller for such an apparatus and a method for controlling a structure testing apparatus in which operation of a direct drive electromagnetic actuator is continuously auto-tuned during a test, so that the test load applied to a specimen during the test is the correct, desired load according to the current specimen parameters including stiffness. Forward and feedback control gains are repeatedly recalculated during the test in response to monitored specimen parameters. |
