The twin-rotor system demonstrates the principles of a non-linear MIMO (multiple input, multiple output) system, with significant cross- coupling. It‘s behaviour resembles a helicopter, but the angle of attack of the rotors is fixed and the aerodynamic forces are controlled by varying the speeds of the motors. Significant cross-coupling is observed between the actions of the rotors, with each rotor influencing both angle positions. Using MATLAB™ (not supplied) together with the detailed training manuals supplied by Feedback and an Advantech PCI card which creates an impressive digital control system development environment, the user is guided through the design process using phenomenological process models, dynamics analysis, discrete models identification, controller design, controller tests on the model, controller implementationin real-time applications, implementation of various control strategies and data visualization.

The equipment set incorporates student experiments which can be carried out in a laboratory safely using safety extra-low voltage. Experiment instructions are contained in a manual in either printed or digital form.

A MATLAB™ license is required for this trial and is not included in the scope of delivery.
The equipment can require additional software modules.
