The invention is a control system for generating time modulated pulse signals to effect movement of a doser type actuator. The control system is characterized in that it includes an augmenter circuit which generates a first correction signal additive to scheduled control signals when the actuator fails to respond or has a response below a predetermined limit to an actuating pulse, a second correction circuit which generates a correction signal proportional to the magnitude of the first movement of the actuator response to a pulse signal for reducing the magnitude of the pulse signal in proportion to the magnitude of the movement, and a gating signal or circuit which blocks said first and second correction signal generating circuits generating the augmentation signal when the movement of the actuator in response to a pulse signal is negative or above a predetermined limit, when the positional error changes direction, or when the actuator position is within the desired deadband limits.
