Design of self-tuning fuzzy logic controller for the control of an unknown industrial process

An improvement over the existing conventional fuzzy logic approach, based on a self-tuning fuzzy logic controller (FLC), for the design of a temperature control process, capable of providing optimal performance over the entire operating range of the process, was proposed. Since an optimum response of the FLC can be expected only for a limited range of inputs, tuning the input and output gains is done here for various range of inputs. The proposed control system has the advantages of self-tuning FLC schemes. To evaluate the performance of the proposed control system methods, the results from the simulation of the process are presented.
