Quanser Rotary Flexible Link



Introduce Students to Vibration Analysis and Resonance Control Concepts

The Rotary Flexible Link module is ideal to introduce various control concepts related to vibration analysis and resonance. You can use it to demonstrate real-life control challenges encountered in large, lightweight structures that exhibit flexibilities and require feedback control for improved performance.

The Rotary Flexible Link module attaches to the Rotary Servo Base Unit (SRV02). Using this experiment, students learn to:

  • find the stiffness experimentally
  • use Lagrange to develop the system model
  • develop and implement a feedback control using the linear-quadratic regulator

In addition to teaching intermediate control concepts, the Rotary Flexible Link can be used for research in various areas, including fuzzy logic, robust control and optimal control.

How It Works

The Rotary Flexible Link module consists of a strain gage which is held at the clamped end of a thin stainless steel flexible link. The DC motor on the Rotary Servo Base Unit is used to rotate the flexible link from one end in the horizontal plane.

The motor end of the link is instrumented with a strain gage that can detect the deflection of the tip. The strain gage outputs an analog signal proportional to the deflection of the link.
