Title: Control system for controlling at least one variable of a process as well as a use of such a control system

Abstract: In a control system for controlling at least one variable (TIT.sub.m) of a process, the at least one variable (TIT.sub.m) being calculated from a multiplicity of measured process variables (TAT.sub.m, p.sub.Cm), the measured process variables (TAT.sub.m, p.sub.Cm) in each case being measured via associated measuring sections (18, 19), the transfer functions (G.sub.2 (s), G.sub.1 (s)) of which have a different time response, an improvement in particular during transient actions is achieved in that, to avoid instability, correction means (21) which equalize the different time responses of the individual measuring sections (18, 19) are provided.
