The friction and backlash units can be used to add these corresponding effects to an output shaft. This permits the user to study the effects of real backlash and friction – not simulated. This lends itself well to control engineers who want to test their friction and backlash compensation or identification schemes.
To add to the list of experiments that can be performed on this device, a Web Winding Transport Module and a Multi-DOF Torsion Module are available. The web winding module can be added to the base IMDU system to convert the plant into a paper machine simulation. In this configuration, the goal is to process the paper as fast as possible without tearing the product. This is done by adjusting the tension and the rate of the spindles.
