Keywords: frequency domain PI-like process FLC design, MATLAB, robust performance, temperature control, time delay, tuning algorithm

Abstract: The robustness of the systems with fuzzy logic controllers (FLC) has lately focused the attention of researchers in relation with the expansion of their industrial application. The contemporary complex, nonlinear, time varying processes with time delay and various disturbances and the high demands for their control require to account for system stability and robustness in the FLC’s design. The simplicity of the design is of great importance in connection to its easy practical application.The aim of the present investigation is to develop a generalised procedure for the design of various PI-like FLCs with regard to system performance robustness and to compare the robustness of the control systems. The approach is developed for PI incremental and position FLCs based on the single input fuzzy controller (SIFC), Popov stability and Morari robustness and considers the control of industrial plants with time delay and model uncertainty. The results are applied for furnace temperature control.
