The Controller Switching Technology Software is a software add-on for LabVIEW. The add-on features a control algorithm that can work as a proportional-integral-derivative (PID) controller, observer-based state controller, linear-quadratic regulator (LQR) controller, and more. The Controller Switching Technology Software supports automatic and bumpless switching between controllers. You can apply the controller algorithm as VIs in LabVIEW software for real-time and non-real-time applications and directly use them with real-time hardware including PXI, CompactRIO, and Compact FieldPoint modules.You can also use the Industry Feedback Controller directly within VeriStand to configure real-time testing applications.
