This experiment is the virtual version of the rotary flexible joint.

It consists of a rotating arm attached with springs to a rotating servo base unit. The goal is to control the angle of the arm with respect to a fixed frame of reference. Considering the springs and the actuator, i.e. electric motor, physical limitations, a dedicated controller must be design to avoid vibrations and guarantee a fast and accurate positioning of the arm.
