National Instruments' LabVIEW graphical development environment now extends to the design, implementation and testing of control systems. Several new toolkits have been added, featuring graphical tools such as root-locus and Bode plots to aid the design of a host of applications, from adaptive cruise control to precision machine control systems. Also included are a simulation module and state diagram toolkit, which can be used to verify controller performance and simulate their dynamics offline, or implement them in real time hardware. The integral I/O capability and determinism of LabVIEW allows these models to be downloaded to real time targets for rapid prototyping and embedding, using NI's CompactRIO FPGA based system, or hardware-in-the-loop testing using real time PXI targets.
