Same as the physical Rotary Flexible Link, the virtual system features a stainless-steel flexible beam with a strain gage mounted on the motor end of the link that can detect the deflection of the tip of the beam. In this experiment, students learn how to find the stiffness experimentally, and use Lagrange to develop the system model. This is then used to develop a feedback control using a linear-quadratic regulator, where the tip of a beam tracks a desired command while minimizing link deflection. This virtual experiment is ideal for the analysis and control of vibrations encountered in large, lightweight robotic structures that exhibit flexibilities and require feedback control for improved performance.
