Analysis for Control and Simulation Applications

Control applications often require advanced analysis routines as part of the control algorithm. Use these analysis routines for filtering input data, signal processing, or inline decision making. LabVIEW offers analysis routines that easily fit into control applications with point-by-point execution. Point-by-point analysis is essential when dealing with control and simulation processes where high-speed, deterministic, point-by-point data acquisition is present. The point-by-point approach simplifies the design, implementation, and testing process, because the flow of the application closely matches the natural flow of the real-world processes that the application is monitoring and controlling.

Advantages of point-by-point analysis routines include:
  • Deterministic time intervals
  • Analysis on acquired sample right after acquisition
  • Single values and waveforms
  • Reduced time delay between acquisition and generation of processed waveform
Functions designed specifically for real-time control, simulation, and signal processing applications include:
  • Array Operations
  • Filters
  • Fitting
  • Frequency Domain
  • Linear Algebra
  • Probability and Statistics
  • Signal Generation
  • Time Domain

Add-On Tools Examples:

"The short development and testing time frame resulted in exceptional cost savings. Based on the author's similar amount of experience with syntactical languages, it is estimated that LabVIEW saved at least one year of development time. Using the simulation VIs saved hundreds of hours of flight-testing at ~$1000/hr. Additionally, between several days and several weeks of effort is saved every time the system is employed." - Helicopter-Borne RF Tower Antenna Verification System
