Modeling, Simulation, and Control of a Twin-Rotor MIMO System

The PXI system fully controlled the physical model, simulating the discrete state-space controller.

"LabVIEW and the PXI system gave us an advantage and the opportunity to complete the project step by step. We learned the inner states of the complex system and observed changes in behavior when we changed the control values."

- Christoph Gabriel, Universidad Politécnica de Valencia

The Challenge:
Simulating a nonlinear, hard-coupled dynamic sixth-order system for control design, and controlling the process using a digital observer.

The Solution:
Using a real-time loop in the NI LabVIEW graphical programming environment to simulate a deployed model, controlling it through another loop where the controller is deployed, and subsequently controlling a deployed model by the controller loop using LabVIEW with two NI data acquisition (DAQ) extension cards to connect the model to the NI PXI-1002 chassis.
