QLabs Virtual Rotary Flexible Link
Virtual platform for distance and blended undergraduate control systems courses
QLabs Virtual Rotary Flexible Link is a fully instrumented, dynamically accurate digital twin of the Quanser Rotary Flexible Link system. It behaves in the same way as the physical hardware and can be measured and controlled using MATLAB®/Simulink® and other development environments. With QLabs Virtual Rotary Flexible Link, you can enrich your lectures and activities in traditional labs, or bring credible, authentic model-based lab experiences into your distance and online control systems course.
QLabs Virtual Rotary Flexible Link is available as a 12-month, multi-seat subscription. The platform is compatible with the physical Rotary Flexible Link curriculum, which covers various modelling and control topics.
Product Details
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.
