In the process of design, industrial production and operation of technical objects there accumulates a significant amount of information. It can be used for the development of mathematical algorithms and programs for realization of automated computer control of technical objects. Because of the complexities in mathematical formalization of the aprioristic information, difficulties arise, which does not always allow using it actively in mathematical models for the estimations of parameters obtained at separate stages of processing of the numerical information about measured of transients. As the formed mathematical models are based on the theory of technical objects identification, the dependence of the computing stability of algorithms Therefore, it is necessary to use equation systems with reasonably low orders. Such objective can be achieved due to the application of filtration of decomposition of autoregressive function. The algorithm of the objective control of technical objects is offered on form a algorithm by using the theory of pattern recognition. The recognition models as part of control algorithm may be built on the base of Fourier model. This results in efficiency algorithms especially in test procedures
