INTEGRAL CONTROLLER Russian patent published in 1994 - IPC

FIELD: automatic controllers. SUBSTANCE: integral controller uses a DC amplifier, first scaling resistor, whose first lead is connected to the cathode of the first diode, whose anode is connected to the cathode of the second diode and to the first plate of the first integrating capacitor, second scaling resistor, whose first lead is connected to the first lead of the first scaling resistor and anode of the third diode, whose cathode is connected to the anode of the fourth diode and to the first plate of the second integrating capacitor. The controller has a unit for discrimination of positive and negative deviations of control signal from its mean current value, whose input is connected to the output of the DC amplifier, which serves as the controller output, the outputs of the unit for discrimination of positive and negative deviations of control signal from its mean current value are connected to the second plates of the first and second integrating capacitors respectively, the anode of the second and cathode of the fourth diodes are connected to the common bus of the controller, the second lead of the first scaling resistor serves as the "Assignment" input of the controller, the second lead of the second scaling resistor serves as the "Controlled variable" input of the controller. The unit for discrimination of positive and negative deviations of control signal from its mean current value has the fifth and sixth diodes, whose anodes and cathodes serve as the unit input, the cathode of the fifth diode via the third scaling resistor is connected to the first plate of the third capacitor, which via the fourth scaling resistor is connected to the anode of the sixth diode, the second plate of the third capacitor is connected to the common bus of the controller, and the cathode of the fifth and anode of the sixth diodes serve as the outputs of the unit for discrimination of positive and negative deviations of control signal from its mean current value. EFFECT: enhanced speed of response and stability margin, as well as decreased overshoot. 2 dwg
