An identification of parameters on a hybrid computer

The authors describe in this paper some findings concerning the identification of parameters of a chemical process. This problem was solved by several optimization methods on various computers and on an hybrid computer. Comparison is made of the obtained results and of the computation times. Major parameter identification problems, which require a great many integrations o f differential or partial derivatives equation systems, should be processed on a hybrid computer. This type o f problem is very well adapted to hybrid techniques since an analog computer serves as a parallel integration operator, non existent in a digital computer.
