The use of hybrid computers for system-parameter estimation

This paper is devoted to the question in what way system-parameter estimation problems can be solved by means of hybrid equipment and what approaches are best suited for such problems.The combination of an analog model of the system under study and the digital computer taking care of the adjustment of that model is still an attractive scheme, in spite of the strong competition due to the rapid development of purely digital techniques.Advantages and problems are pointed out. Some illustrative examples are summarized.
