| description | 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 (4), and an electronic control unit. The control unit comprises a mathematical module (2), model-related to the control valve (4), for adjusting the valve position, and the gas control valve (4) has in-built sensors for gas variables and valve position, the control system adjusting the control valve (4) in linear proportion to a desired gas-flow signal to be supplied to the control unit. The mathematical module (2) comprises a flow submodule (2.1), a mechanical submodule (2.2) and a valve-position submodule (2.3), and the flow submodule (2.1) receives, at its inputs, the desired gas-flow signal (Qgn) and gas variables originating from the valve sensors and supplies, at its output, a signal relating to the through-flow area of the valve (A), to the mechanical submodule (2.2). Said mechanical submodule (2.2) contains mechanical valve parameters processed therein and supplies, at its output, a valve-position signal (S) to the valve-position submodule (2.3), which receives a position signal (Sh) originating from the valve-position sensor. The valve sensors for the gas variables comprise a sensor for the gas inlet pressure (P1), a sensor for the gas inlet temperature (T1) and a sensor for the gas pressure difference across the valve ( DELTA P). The gas control valve (4) 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. |
