  • Publication number: 20150073601
    Abstract: A test system and a method includes applying a test drive signal to a physical test rig having a compliant actuator assembly for imparting loads to a test specimen. An actual response signal of the physical test rig and the test specimen to the test drive signal is obtained and an error as a function of the actual response signal and a selected response signal is calculated. If the error has not reached a selected threshold a new drive signal based on the error and a relaxation gain factor is obtained. The new drive signal is obtained and applied until the error reaches the selected threshold.
