Application of Adaptive Techniques to Problems in Control and Communication.

Abstract

It was decided at Yale in 1980 that the control problem should be reformulated with more realistic objectives, allowing less restrictive assumptions to be made regarding the plant. For example, in many situations, where the error between plant output and model output cannot be made to tend to zero asymptotically, a reasonable objective would be to assure the boundedness of the output error as well as all the signals in the adaptive loop. Such considerations eventually led to the study of bounded error adaptive control problems. Plants with nonlinearities, output disturbances and time-varying parameters fall into this category. The work that has been in progress during the past eighteen months at Yale is concerned with the development of procedures for stable identification and control of systems with various degrees of uncertainty. Direct and indirect control techniques for systems with many control inputs and parameters are being investigated and methods of combining different techniques to obtain improved performance in practical applications are being examined.
