Abstract : The main areas of research which have been investigated during the third year of the Grant are optimal discrete-time self adaptive filters, optimal adaptive linear systems with unknown input gains, neutrality and separability, properties of dual control algorithms, the controllability of fixed linear systems, compatible suboptimal controllers for the constrained dynamic compensation of linear systems and multi-reflexive regulation of heart rate during lung inflation. In the case of discrete-time filters, a numerical algorithm was derived for calculating the output of the filter which adapts to its own noise. The derivation of the optimal control law for linear systems with unknown input gains is another new result of this research effort. Results of the investigation in dual control include the establishment of a separation property for certain problems of identification and control as well as the establishment of certain neutrality and separability properties of dual control algorithms. Considerable insight into the multi-reflex regulation of heart rate has been gained through extensive experimental work still in progress. A new controller design procedure for asymptotically optimal linear systems with one input has been established. This procedure shows definite advantages in comparison with known procedures which are based on the theory of observers. (Author)
