Once the designer has chosen the performance criterion, it must be minimized, which in a data-driven control design will be done using only input-output data collected from the system. It is possible in many situations to perform this minimization in only “one-shot”, that is, with only one batch of data collected in only one operating condition. These “one-shot” solutions, which are the most convenient, are the subject of Chap. 3. The virtual reference feedback tuning method (VRFT, for short) is presented and its statistical properties—consistency, variance—are demonstrated. Its extension to nonminimum phase processes is also presented. A number of simulation studies illustrate the properties of VRFT.
