Quanser Hexapod Helps in Development of a Seismic Isolator at BarcelonaTech

A research group at The Polytechnic University of Catalonia's (also known as BarcelonaTech) Control, Dynamics and Applications Lab (CoDAlab) led by Dr. Francesc Pozo works on a system that can help better protect buildings and infrastructure from earthquakes. The roll-n-cage (RNC) anti-vibration device placed between the building and the ground can reduce motion induced in buildings and bridges by earthquakes or other vibration sources. To model the RNC device, Dr. Pozo and his group uses Quanser Hexapod. Watch this video from their lab:

In this application, the researchers attached a force-torque sensor to the upper plate of the Hexapod. The sensor measures the force and torque of the ball placed on the sliding surface. The group developed two control algorithms to control the position of the ball and place it in the middle of the platform as quickly as possible: a standard PID control and a fuzzy-logic control.

"I consider Quanser as one of the leading companies in the field of design and manufacture of systems to help instructors to teach," says Dr. Pozo, "but these devices can also be used to test control algorithms." His research group is using several other Quanser devices, such as Shake Table II to generate a horizontal motion to modeland identify a MR damper attached to the Shake Table surface.
