Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Determination parameters of numeral models of dynamic links analog automatic control systems Shilin A.N., Krutyakova O.A. In the article the analysis of errors of numeral design of the automatic control systems is conducted by the methods of z-forms and operator-discrete method. The results of analysis allow more grounded to choose methods numeral design and parameters of numeral models of dynamic links of analog automatic control systems. Key words: digital automatic control systems, z-simulation for analog automatic control systems, errors of z-simulation, choice of frequency of discrete at z – simulation.
