INTEGRAL CONTROLLER Russian patent published in 1994 - IPC

FIELD: integral 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 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 units for discrimination of positive and negative deviations of control signal from its mean current value, unit for forming the mean current value of control signal and two current generators provided with supply coupling via balancing resistors; the input of the unit for forming the mean current value of control signal is connected to the output of the DC amplifier, and the output - to the first inputs of the units for discrimination of positive and negative deviations of control signal from its mean current value, whose second inputs are connected to the output of the DC amplifier, and the outputs - to the second plates of the second and first integrating capacitors respectively, and to the outputs of the first and second current generators, whose inputs are connected to the negative and positive terminals of the power source respectively, the first leads of the first and second scaling resistors are connected to the inverting input of the DC amplifier, 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 output of the DC amplifier serves as the controller output. EFFECT: enhanced accuracy of controller. 1 dwg
