A digital control system includes sensors, a multiplexer, an A-D converter, an input register, an arithmetic unit and a memory unit, an output register, an output unit, and actuators. The digital control system thus formed has an initializing routine stored in the memory unit in addition to the programs to execute normal control operations. This routine is executed immediately after the control system starts, so that predetermined temporary initial values can be set in the input or output register in order to obtain stable arithmetic operation results or to output a stable control signal even when the engine is not yet ready for outputting stable information. The control system thus improved can control an internal combustion engine stably immediately after the engine is started.
