Abstract:
A method of real-time optimization of a control device provided with a fuzzy inference system for controlling a machine, said fuzzy inference system comprising a matrix of fuzzy rules which are regulated by preselected parameters, said method comprising the steps of:operating the machine using the fuzzy inference system of the control device; optimizing in real-time the input-output relationship of the fuzzy inference system by: (i) selecting a section from the fuzzy rule matrix including multiple sections, and (ii) revising the fuzzy rule matrix by extracting the section from the matrix and coding elements of the section into chromosomes, said chromosomes being subjected to evolutionary computation, wherein at least one fitted individual is selected based on a user's ultimate choice or a pre-selected target; and operating the machine using the optimized fuzzy inference system.
