Abstract
This thesis is concerned with a method to automatically identify parameters of an unknown or changing system. The method uses a model of the system. The parameters of the model are perturbed about their initial values. The output of the model is subtracted from the output of the system, and this difference manipulated to produce a signal which changes the model parameter until the model and system outputs are approximately equal. The use of a second order differential equation as a model is discussed. In particular, the identifying scheme is shown to be unstable for certain types of system inputs. The problem of trying to adjust one model parameter when others are not properly adjusted is treated. The behavior of the identifier when the system is of the third order is discussed. The thesis contains an analysis of the time-varying equations and of the equivalent transfer function proposed for the adaptive loop. Results of simulation on an analog computer are presented.
