Abstract: To prevent surge of a turbocompressor (K), a anti-surge valve (27) provided at the compressor outlet is controlled by a controller (R). The input signal for the controller (R) is generated as a function of the instantaneous flow and the end pressure of the compressor (K) such that the controller responds more slowly to working point shifts in the direction of the surge limit line and more rapidly to working point shifts in the opposite direction. This is achieved by arranging an asymmetric time element or a gradient sensor in the circuit generating the input signal for the controller (R).
