DETERMINATION OF DYNAMIC PARAMETERS FOR ADAPTIVE ACTUATOR CONTROL USING A MECHANICAL TESTING DEVICE

摘要

A method for adaptive control of an actuator during a test of a specimen using a mechanical testing device, the method comprising: applying a mechanical load to the specimen with the actuator, resulting in receiving a load sensor signal from a load sensor and a displacement sensor signal from a displacement sensor; determining a plurality of dynamic characteristics of the mechanical testing device throughout a length of the test from data received from the load sensor signal and the displacement sensor signal; and controlling the actuator based on the plurality of dynamic characteristics to adapt the actuator to track a desired performance of the actuator.
