2. BUILDING THE DISCRETE MODEL OF AGGREGATIVE OBJECT WITH INTERVAL AGGREGATIVE DISCREET INTERVAL

Aggregative discrete control object, consisting of discrete model of direct channel, discrete model of continuous technical object and discrete model of back channel, is characterized by the fact that at variation of system discreet interval, parameters are changed only in discrete model of continuous technical object, so model presentation of aggregative discrete object in case of interval realization of discreet interval will possess only one interval matrix component, which is a state matrix. Building of discrete model of aggregative object with interval aggregative discreet interval can be realized according algorithm.

The Algorithm:

1. Form the requirements to quality factors of the system of digital remote control of continuous technical object in transient and stabilized state.

2. Evaluate n_p lengths used in  code transformation devices and duration t of the elementary signal (bits) used in channel environment of binary codes on basis of capacity of telematic protocol (TMP) in accordance with formula: t = (c)^-1.

3. Form the format (n, k) of nonjammable code, in which k=nр - a number of data bits PZK, n=k+m - a full number of code bits, correcting s-fold errors during transmission of control signal codes through direct channel and output measurement codes through back channel relationship according to the task of remote control of continuous technical object under   

and 

4.  Form interval aggregative discreet interval for binary channel (DKS) without interference according to correlation

5. Enter hypothesis on absence of control signal output delay from microcomputer (microcontroller) and in its digital-analog and analog-digital transformation in direct and back channel device which allows to consider equal the lengths of technical object continuous model state vector                                  ,                                                                       (4)
