Abstract
A control system is provided for a variable geometry turbocharger of an internal combustion engine including a turbine which is operated in response to an exhaust gas and a compressor connected to the turbine to supply the engine with supercharging compressor. The control system calculates a control value on the basis of the rotational speed of the engine and the load on the engine so as to control the exhaust gas to be supplied to the turbine. In addition, the control system is provided with a limiting means to limit the change of the control value within a predetermined range.
