SENSITIVITY FUNCTIONS FOR MULTIDIMENSIONAL LINEAR DISCRETE MODELS IN ADAPTIVE SYSTEMS

A method of minimizing the number of equations to be solved in calculating the output of a model and all the sensitivity functions in adaptive systems when their functioning time is long is proposed. The models in question are given in the form of a system of linear difference equations. The finding of points of sensitivity in dynamic equations is based on the use of an operator form of writing discrete equations in the time domain. Block diagrams of the algorithms for calculating the output of a model and the sensitivity functions are given.
