The block diagrams as engineering means for closed loop control, which have been established by classic control theory for decades, are replaced in the above mentioned book by networks, the signals are replaced by data.It corresponds to the „Industry 4.0“ and to the structure of today’s automatic control systems.Thereby a classic closed loop is treated not isolated from other elements of nowadays automation like bus communication and process logical control, and is completed in proposed book with new control elements, so called data stream managers (DSM).The proposed book treats the control theory systematically like it is done in classical books considering the new concept of data management.The theory is accompanied in the book with examples, exercises with solutions and MATLAB®-simulations.
