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 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 (SI FC), Popov stability and Morari robustness and considers the control of industrial plants with time delay and model uncertainty. The main contributions are:1) a generalised design procedure for FLCs accounting for system stability and robustness;2) FLCs’ general tuning algorithm.The results are applied for the stabilisation of the air temperature in a furnace using MATLAB™.
