Abstract:

Six papers were published during the period of this report. Efforts were continued on approximation of delay systems with applications to optimal control and parameter identification. Studies are being made on the effects of delays on difference and differential-difference equations. Research has been centered on the stability properties of infinite-dimensional systems. Work has been completed on illustrating the effect of nonlinearities of controllability and stability and the tradeoffs required in order to meet control objectives and constraints on the state variables.
