PURPOSE:To enable the formation of a combustion controlling device which comprises a transient response preventing means, being prevented from the occurrence of mulfunction during the primary stage of ignition, by providing an output control means which, during the initial stage of ignition, controls the set level of a saturation preventing means to a minimum value during a given time. CONSTITUTION:A saturation preventing means 5 is provided, the means being functioned such that an integrator AI is prevented from saturation through feedback of an output V to the input side of the integrator AI so that, in case the output V is outputted at a value exceeding a reference voltage Va, the output V of the integrator AI is maintained at the reference voltage Va irrespective of the input voltage of the integrator. Meanwhile, an output control means 6 is provided, the means controlling such that during the primary stage of ignition, the starting takes place by means of an ignition signal St, the action of a PID control means 1 is brought to a temporary stop so that the output V of the PID control means 1 is maintained at a minimum value Vo lower than the reference voltage Va, and the set level of the saturation preventing means 5 is adjusted to the minimum value Vo despite of the given value Va until a given tau, in which such temporary stop takes place, elapsed. |
