Schematic and algorithmic methods of elimination influence of interference on accuracy of intellectual interfaces of the technological process

Abstract

The article discusses the main requirements for an intelligent measuring channel in the design of automated monitoring and control systems. Methods for estimating errors and noise are analyzed, constituent groups are classified, and some methods for calculating the noise of measuring instruments and measuring modules of automatic control systems are given.

Computer simulation and optimization of the oxidation process in the production of nitric acid in the Aspen Plus environment

“…Influence of water consumption on irrigation of the absorption column and consumption and consumption of the final product HNO3 Figure 6. The figure shows an increase in water consumption for irrigation increases the consumption of nitric acid [17][18][19][20].…”

Adaptability analysis of linear continuous control systems with reference model

“…) Taking into account the notation (15), the last equation can be represented as Δ � � 𝐴𝐴 � Δ � 𝑢𝑢 � Δ𝑘𝑘 � � (16) So, the adaptive control system in new variables is described by equations (16). As a candidate for the Lyapunov function, we consider the quadratic form…”

“…Substituting into the right side of the expression for the derivatives from the equations of the adaptive control system (18) and ( 16), we obtain [10][11][12][13][14][15][16][17][18] 𝑉𝑉 � �Δ,…”

Construction of continuous and discrete non-linear prognostic models of the control system for the process of grinding ore materials

“…The constant D in equation ( 25) is determined from the difference between the measured value at the output of the object and the value of this value calculated by the model � � 𝐹𝐹 ̑� � 𝐹𝐹 � in τ(k), which is the result of additive step disturbances that persist throughout the entire predicted interval [15][16][17][18][19][20].…”
