Abstract : A major goal of research on physiologic processes is the derivation of a mathematical model of the system under test. With the growth of modern control theory, mathematical methods have been and are being developed to reliably obtain parameters of an estimated system from experimental data. The report investigates the modulating function method of system identification first described by Loeb and Cahen. The method is applicable to systems described by linear differential equations, and tests of the method show that it is suitable for use with both analytic and operational data. Certain restrictions exist on the method, however. To test the method, a general model of the closed-loop carotid blood pressure control system was derived and tested. (Author)
