Abstract

An algorithm for estimating the state vector of controlled plants in the class of bandlimited functions with a cutoff regularizing function is proposed which is more effective and accurate than available algorithms. The effect of errors in assigning samples of the differentiated functions on the estimate quality is evaluated, and the methodical error of the algorithm is analyzed.
