PID CONTROLLER WITH ADDITIONAL CONTROL ACTION

摘要

The invention relates to automatic controllers with additional control action and can be used for technological object control with delay. A PID controller with additional control action comprises a comparison unit, functional units of PID conversion with corresponding adjustment devices which output are connected to three inputs of first adder which output is a first input of second adder. The controller further comprises second differentiating unit which output is connected to second input of the second adder, and output of the second adder is a controller output, and input of second differentiating unit is connected to output of the first adder. The invention provides reducing the value of maximum dynamic deviation in transient modes of automatic control systems and enhancing stability factor thereof due to additional control action of differentiator, and controller configuration is simplified.
