Optimal adaptive control systems for devices having delay (Q1090651)

It is argued that convergence cannot characterize the quality of the adaptation algorithms and thus digital modelling plays a major role by allowing an adaptive control algorithm to be compared with various adaptation algorithms. Optimal adaptation algorithms have the highest possible rate of convergence which is valid to evaluate their quality. A general approach to solving the problem of synthesizing an adaptive discrete control algorithm is presented in the paper involving an extended squared-error criterion and optimal predictor structures. Optimal adaptation algorithms are established and their properties and differences are explained.
