Abstract :
This paper deals with implementation of one self tuning controller into PLC´s (programmable logic controller) library. The polynomial method is used and the parameters of controller are derived using /spl delta/-model and the pole placement approach. The recursive least-squares method and directional forgetting is used to estimate the parameters of the /spl delta/-model. The algorithm was implemented into library of PLC Tecomat, product of Teco, Inc. Company. The laboratory tests proved that algorithm implementation was successful.
