Noise Effect on Operation of Step Variable Parameters Extremal Systems

The analysis of effect of normal additive noise at the output of a plant both on steady state and transient behaviour of the following variants of step extremal systems is carried out: a) with constant operation step and with variable number of storages before it; b) with variable operation step and with constant, number of storages; c) with variable operation step and variable number of storages. It is shown that the systems suggested can provide for more strict requirements laid down simultaniously before values of average search time and steady – state error of extremum followup than the constant parameter systems.
