Dear reader,

As you might have learned Adept Scientific was placed under administration recently.

Alfasoft AB has acquired several assets of Adept Scientific Limited with the intention to continue providing services on the best scientific software tools available. Please allow us a few days to reconfigure this web store for you. For inquires about Mathcad please send an email to info@alfasoft.com.

Alfasoft AB has provided high end scientific software in the Nordic countries since 1989 and we would be honored to give the same service to you.

Yours Sincerely,
Roberth Hoff-Olsen

Rotary Double Inverted Pendulum

501-800-600

Take the Classic Inverted Pendulum Challenge to the Next Level

The Rotary Double Inverted Pendulum module is ideal to introduce intermediate and advanced control concepts, taking the classic single inverted pendulum challenge to the next level of complexity. You can use it to demonstrate real-world control challenges related, for example, to takeoff stabilization of a multi-stage rocket. The Rotary Double Inverted Pendulum module attaches to the Rotary Servo Base Unit. Using this experiment, students learn to:

  • obtain a state-space representation of the open-loop system
  • design a state-feedback gain for the closed-loop system using LQR optimization
  • simulate the system and ensure it is stabilized using the designed state-feedback control
  • implement the state-feedback controller and evaluate the system performance

In addition to teaching advanced control concepts, the Rotary Double Inverted Pendulum can be used for research in various areas, including nonlinear control and optimal control.

How It Works

The Double Inverted Pendulum module is composed of a rotary arm that attaches to the Rotary Servo Base Unit, a short 7-inch bottom blue rod, an encoder hinge, and the top 12-inch blue rod. The balance control computes a voltage based on the angle measurements from the encoders. This control voltage signal is amplified and applied to the Servo motor. The rotary arm moves accordingly to balance the two links and the process repeats itself.

Quanser-developed Courseware Included

The Double Inverted Pendulum module comes with Quanser-developed courseware. The comprehensive Laboratory Guide, accompanied with quick start resources, User Manual, pre-designed controllers and system model allow you to get your lab running faster, saving months of time typically required to develop lab materials.

What do our Customers say about us?

It was about as perfect as a teaching seminar could be. Moved at the correct pace and encompasses a good amount of information

Origin lets you zoom in on an an area of the plot easily without having to rescale manually. I also love the data reader feature where you can follow a line or curve and view the exact coordinate values. Thanks for an awesome product!
