FIELD: engines and pumps.
SUBSTANCE: engine standard pickup readings are read to be compared by comparator with control signal describing gas temperature in combustion chamber. Resultant read-minus-control signal is sent to proportioner to control fuel flow rate. Note here that each signal of pickups is taken logarithm of by formula ln(Xi) where Xi are pickup readings. Thereafter, each signal is amplified in proportion to degree of parametre Ci*lnXi in regressional relationship 
Obtained signals are summed in defined relationship lnT*"Г"=Co+Σ(Ci*lnXi) and, prior to sending obtained signal to comparator, comparison results are exponentiated in relationship T*"Г"=exp(lnT*"Г").
EFFECT: higher accuracy of gas turbine engine control.
