The invention relates to automatic regulators with additional regulating action which can be used for delay time-technological property management.The object of the invention is in improvement of PID controller to reduce maximum dynamical deviation value in transient modes of automatic regulation systems and to increase stability margin due to additional regulating action as well as reduction of response time.A proportional-integral differential controller with additional regulating action comprises a comparing unit, functional units of proportional, integral and differential transformation with corresponding devices for setting thereof. Inputs of the units are connected to three inputs of the first adder, which output is connected to the first input of the second adder, as well to the input of the first inverter, and the output of this inverter is connected to the input of the functional unit, which output is connected to the second input of the second adder as well as to the input of the second inverter which output is connected to the delay unit and the output of this delay unit is connected to the third input of the second adder which additionally has the third adder, which first input is connected to the output of the second adder, and to the second input of the third adder the output of the second differentiating unit is connected, which input is connected to the output of the proportional transformation unit. The third unit of differential transformation is used as a functional unit, and the output of the third adder is an output of this controller. |
