Linear Double Inverted Pendulum

858-800-600

Take the Classic Inverted Pendulum Challenge to the Next Level

The Linear 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 Linear Double Inverted Pendulum module is used attached to the Linear Servo Base Unit. With this setup students learn how to:

  • obtain a state-space representation of the open-loop system
  • design a state-feedback controller to balance a double pendulum, while tracking the linear servo cart position
  • simulate the system and use the designed state-feedback controller to ensure the system is stabilized
  • implement the controller and evaluate the system’s performance

In addition to teaching intermediate control concepts, the Linear Flexible Inverted Pendulum can be used for research in various areas, including robust and optimal control.

How It Works

The Double Inverted Pendulum module consists of two aluminum, precision-machined blue rods; one seven inches long and the other 12 inches long. The module easily attaches to the front pendulum shaft on the Linear Servo Base Unit cart and is free to rotate 360 degrees. The short link angle is sensed using the Linear Servo pendulum shaft encoder, while the medium length link is measured using the middle encoder mounted on the Linear Double Inverted Pendulum itself.

Based on the cart position and the pendulum angles, the balance control computes a voltage that is applied to the cart motor. The cart moves back and forth to balances the two pendulums and keep them in the upright, vertical position.

Quanser-developed Courseware Included

The Linear Double Inverted Pendulum comes with Quanser-developed courseware. The Laboratory Guide, together with quick start resources, a comprehensive User Manual, pre-designed controllers and a 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?

THANK YOU – you are a star and have saved my thesis! Your instructions worked perfectly. If I am purchasing upgrades I will definitely go to Adept now I know what level support you can provide.

CB, Plymouth, UK

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

I can only say I wish all suppliers were as helpful as you.

CP, Newport, UK

I am impressed by the level of support your company provides, and the list of software you offer looks very good indeed.
