The 3 DOF Gyroscope is a dynamically diverse experimental platform ideal for study of rotational dynamics principles related to the real-life applications including altitude control, momentum wheel control, navigation, satellite orientation, auto-pilot systems and technical devices with gyroscopic sensors, such as smart phones, tablets or video game controllers. Students learn how to:
In addition to teaching active control concepts, the 3 DOF Gyroscope can be also used for research in various areas, including nonlinear control and system identification.
How It Works
The 3 DOF Gyroscope utilizes the principles of angular momentum to measure and sustain orientation. This robust system consists of a disk mounted inside an inner blue gimbal which in turn is mounted inside an outer red gimbal. The entire structure is supported by a rectangular silver frame that is free to rotate about its vertical axis of symmetry using a slip ring design. The gimbals are also equipped with slip rings, allowing them to rotate freely and giving the disk three degrees of freedom.
The plant is equipped with four DC motors and four encoders. Separate motors actuate both the disk’s spin axis and the blue and red gimbals. The fourth motor controls the gray rectangular frame which can be used to create a controlled disturbance. Digital position of all the axes is measured using high-resolution optical encoders. Although the gimbals and outer frame are free to rotate, the plant provides the ability to fix any desired axis (outer frame, red and blue gimbals). These different configurations allow for a wide range of experiments to be performed with the 3 DOF Gyroscope – a distinguishing feature, making this plant a valuable addition to a lab.
The 3 DOF Gyroscope comes with Quanser-developed courseware. The comprehensive Laboratory Guide, together with quick start resources, a User Manual, pre-designed controllers and a system model allows you to get your lab running faster, saving months of time typically required to develop lab materials.

To set up your 3 DOF Gyroscope workstation, you need additional components. Quanser engineers recommend:
¹ alternatively, you can use QPIDe or any equivalent NI DAQ device supported by QUARC
² alternatively, you can use two AMPAQ-L2 amplifiers
³ NI cRIO-9074, or NI cRIO-9024 with cRIO-9113 or cRIO-9114 chassis
4 alternatively, you can use Quanser QPIDe
