ABSTRACT:
An anti-surge control of a turbocompressor includes a controller which controls the progressive opening or closing of a blow-off valve as a function of the working point location relative to a blow-off line defined in the characteristic field. A quick opening of the blow-off valve upon the occurrence of a close approach to surge is effective by applying a correction signal to the integral section of the controller.
