Industrial Automatic Control Systems and Controllers Annotation << Back Ensuring the Reliability of Independently Measured Parameters of Technological Flows in Information and Control Systems B.M. Temerbekova The general method of solving the problem of ensuring and controlling the reliability of independently measured parameters of technological material flows based on the method of indeterminate Lagrange multipliers is substantiated and it is shown that the effectiveness of the proposed method can be improved if the values of individual technological parameters of flows are measured in several independent ways. The method of correction of the initial measuring signals in the case of redundant information during the operation of plants in stationary production mode through separate channels is proposed. This technique can be applied provided that the corrected values are determined in a time significantly longer than the dynamic memory of the object, or provided that the dynamic connections of individual channels are fully compensated and, therefore, for the corrected values, the fulfillment of static equations in information control systems is unconditional.
