Optimizing System Response Before Testing
In MTS systems, optimizing system response involves inertial compensation and tuning.
About Inertial Compensation
Inertial error is a result of the unwanted feedback induced by the moving fixture mass mounted to the load
cell. It is important to understand that the unwanted effects of this motion increase exponentially as the
test frequency increases.
