Abstract:
    The invention relates to a process for controlling at least two production units whose outputs are connected in parallel in order to produce a common output flow which is intended to feed a consumer plant. It controls the common output flow as a function of a predetermined target value (u) and includes the steps consisting in measuring at least one variable representing the common output flow; for each unit, determining a control instruction corresponding to one operating state of the unit among a finite set of predetermined operating states; and controlling the units with the control instructions determined. Two variables representing the common output flow are measured and the control instructions are determined by a fuzzy-logic controller.Application to controlling a set of compressors.
