This paper presents the results of experimental analysis of a frequency adaptive controller ChAR-22 in the feedback loop aimed at achieving a desired tolerance level for the plant output. The plant has some unknown parameters; furthermore, an external disturbance affects the plant. A physical plant model (PPM) was used in the experiments as a real plant. The PPM is implemented as an electronic device. Putting the CHAR-22 controller in the feedback loop reduces the system output more than by a factor of ten as compared to the output of the open-loop system.
