Abstract: | One approach to a recursive identification of continuous - time systems was implemented in self - tuning control of a system of interconnected tanks. Since derivatives of input and output variables of continuous - time systems can not be directly measured, differential filters and filtered variables are established to substitute primary variables. The filtered variables are then used in a recursive identification procedure where the classical recursive least squares method is used to identify the system. Results of real ? time experiments are compared to results obtained with an analogical discrete controller. The method was also verified by simulation on a multivariable system in order to verify the algorithm on a system with more complex and complicated structure, where one output is influenced by more inputs. | ||||||||||
