A control system for supplying a gas flow to a gas consumption apparatus, comprising a gas supply pipe which can be connected to the apparatus and which has an electrically controlled gas control valve, and an electronic control unit. The control unit comprises a mathematical module, model-related to the control valve, for adjusting the valve position, and the gas control valve has in-built sensors for gas variables and valve position, the control system adjusting the control valve in linear proportion to a desired gas-flow signal to be supplied to the control unit. The mathematical module comprises a flow submodule, a mechanical submodule and a valve-position submodule, and the flow submodule receives, at its inputs, the desired gas-flow signal and gas variables originating from the valve sensors and supplies, at its output, a signal relating to the through-flow area of the valve, to the mechanical submodule. Said mechanical submodule contains mechanical valve parameters processed therein and supplies, at its output, a valve- position signal to the valve-position submodule, which receives a position signal originating from the valve-position sensor. The valve sensors for the gas variables comprise a sensor for the gas inlet pressure, a sensor for the gas inlet temperature and a sensor for the gas pressure difference across the valve. The gas control valve is designed as a cylindrical hollow slide valve having central gas feed and lateral gas outlet with exponential flow profile, and is provided with an electromagnetic actuator having a wire coil wound on the valve slide in a permanent magnetic field.
