LabVIEW Control Design & Simulation Benefits

• Complete simulation and real-time implementation capability - stay in one environment from design to test to implementation

• Easily create parallel and multirate simulation or control loops, leverage multicore

• Custom user interface to change and observe parameters as simulation or control system is running

• Use VIs or programming structures inside or outside of simulation loops:

• Integrated design and simulation, batch simulation

• DAQ, RIO, Vision, or CAN for I/O

Dr. Andy Clegg, Lead Engineer & ISC Managing Director: “We used the LabVIEW MathScript RT Module to run a textual node containing our m-file code, developed with MATLAB on a desktop, for kinematics on the real-time CompactRIO controller. MathScript has significant benefits for real-time deployment on the CompactRIO controller including determinism, easy debugging, and no extra compilation steps.“

Multi-Modal Rover for Search and Rescue

“With both an FPGA and a PowerPC processor, the Single-Board RIO platform has the flexibility to handle a variety of programming tasks and algorithms in an efficient manner. Onboard Ethernet, combined with a Wi-Fi adapter, enables real-time wireless communication, debugging, and deployment of software”

Industrial HIL – National Oilwell Varco

“Having a simulation of the plant allow us to test our algorithm on the PLC on different working conditions much faster and effectively” - Pål Jacob Nessjøen, development advisor

Challenge. Modeling an industrial pump (including drives, gears, and drill string) and running it on cost effective hardware

Application. Create a test system to evaluate PLC performance before installing it offshore

Products used. LabVIEW, Mathscript and the Control Design and Simulation Module

Developing a Control System to Automatically Position a Split-Hopper Vessel

Application: Build a control system that keeps a ship on a fixed position and heading

Challenge: Design an advanced control system with DGPS, wind, current, gyroscope feedback

Products: PXI, cRIO, RT, LabVIEW Control Design and Simulation Module

Key Benefit: Use a common platform to develop controller and deploy system able to integrate third party information systems.

“We used NI tools because its software allowed us to reuse

the same code from simulation to deployment and its

hardware was reliable” Miguel Taboada, SEAPLACE
