The invention relates to automatic controllers with supplementary regulating action and can be used for controlling technological objects with delay. A PID controller with supplementary regulating action comprises a comparator unit, PID conversion functional units with corresponding setting devices, first and second adders, wherein output of first adder is connected to input of second adder. The controller additionally comprises second differentiating unit which output is connected to input of second adder, and output of second adder is a common output of the controller. According to the invention output of proportional transformation unit is connected to input of second adder, and outputs of integrating unit and first differentiating unit are connected to corresponding inputs of first adder which output is connected to input of second differentiating unit. The invention provides reducing value of maximum dynamic deviation in transient modes of automatic control systems and stabilization of these systems due to supplementary regulating action of second derivative differentiator, and reducing transient control process time. |
