What is meant by proportional controller with integral actuator driver?

The short form "actuating controller" is used to describe a "proportional controller with integral actuator driver". In contrast to the modulating controller, an actuator feedback signal is essential for the actuating controller.
The actuating controller controls the clockwise or anticlockwise movement of the motorized actuator via 2 switching outputs.
The position of the motorized actuator is registered and compared with the manipulating variable (yR) of the proportional controller.
