The invention relates to the field of computing, can be used to assess the state of an object by several parameters with a fuzzy setting of the degree of belonging of possible parameter values to a given state of the object.

The purpose of the invention is the expansion of functionality by analyzing parameter values by a minimum criterion at any given time.

The drawing shows an electrical structural diagram of the device.

The analyzer comprises m connected in series m shift registers 1, the control inputs of which are connected to the output of the GTI 2, m groups of blocks 3 of the memory function of the membership m blocks 4 of determining the minimum value and block 5 of determining the maximum value.

All blocks have the same design as similar blocks of the main device.

A device for assessing the state of an object operates as follows.

The measurements of 1 parameters characterizing the state of the object Sr1 (i - 1, m, j 1 - N, where m is the number of measured parameters, m is the number of register cells). Thus, in the steady state, in each of the registers I-I there are N-samples of the corresponding parameter. Each parameter value corresponds to a value of the membership function:

USi (Si {)

characterizing the j-ro belonging of the value of the 1st parameter to a certain given state of the object.

In each of the groups of blocks 3, the value of the membership function for the current value of Cr1 is calculated. Blocks can be made in the form of ROM and programmed for the corresponding membership function, for example, approximate equality, linear form:

Usi (S | J) max | 0,1 - () |

where is Sol. Oi are the position and span parameters of the membership function, characterizing the value of the parameter corresponding to

0

the unconditional state of the object in a given state, and the scope of the membership function, respectively.

In blocks 4-1-4-t, the minimum values are respectively allocated for each group {SJi, J 1.N} and in blocks 6-1 ... 6-N for each group {SJi, j 1, m}. As a result, two corresponding sets are formed:

{Slmln I 1, m}

{mln {Sr1, j 1, N}} J

{Sjmin J 1. N} {mln {SiJ. i 1, m}}

i

5 The signals of these two sets are fed to the inputs of block 5, in which the maximum signal is extracted:

With max {{Slmln}, {Sjmin}}

0 | j

The resulting estimate lies in the interval (0.1) and determines the degree to which the state of the object belongs to a given one.
