The researching of application a fuzzy controller in a robust control system
The article is devoted to the development of a robust automatic control system with a fuzzy controller. The main feature of a designed control system is pre-processing blocks of input and output in the fuzzy controller. There was made a comparative analysis of control systems with classic and fuzzy controllers. There were made a calculation of the control object parameter values, for which the automatic control system with the traditional PI controller was at the limit of stability. A comparative analysis of the quality of classical and robust control systems shows that the developed robust control system with fuzzy controller is able to maintain the quality of regulation at very considerable uncertainty control object parameters.
