Research will be conducted on the modeling and least squares parameter          identification of nonlinear differential and differential-delay systems         using projected equation error methods.  The projections are designed           to obviate the necessity of dealing with unknown initial or boundary            conditions for time limited input-output data.  Special emphasis is             given to a projection method based on Fourier-type modulating functions         which facilitates utilizing well known Fast Fourier Transform                   techniques at each stage of the least squares identification.  Topics           include delineating and extending the class of nonlinear systems that           are amenable to the projection methods, structure determination                 procedures for the various classes of models, methods for handling              modeling errors, determining optimal inputs for the projected equation          error identification, and incorporating controller parameter update             rules for adaptation in certain nonlinear control systems.
