A Physical Realization of the Minimum Variance Control-Like Algorithm Based on the Real-Life Servomechanism System: a Pilot Case Study

A new form of the minimum variance control algorithm devoted to the physical systems is presented in the paper. A special attention is paid to its practical implementation guaranteeing a maintenance of the technological limitations in the actual process. In such a way, the robust control procedure allows us to obtain the maximum-speed and maximum-accuracy behaviors of a closed-loop system blurred by disturbances. It has turned out that the new approach could compete with the LQ algorithm subjected to the predefined weighting matrices. A real-life servomechanism example confirms a correctness of the new method ultimately addressing a set of the open problems worth future research efforts.
