There are many data processing algorithms to consider when creating a control application. You can create custom control algorithms using LabVIEW. You also can use VIs, such as the LabVIEW Control Design Toolkit VIs, to process control application data. This toolkit offers several libraries that you can use to develop a control application. The most commonly used control algorithm is the PID, but the toolkit also includes tools for fuzzy logic and advanced control algorithms. Fuzzy logic is a method of rule-based decision making used for expert systems and process control to emulate the process of human decision making.
