FIELD: textile industry. SUBSTANCE: device for control of textile machine in changing of properties of textile product has capacitive pickup, two rectifiers, amplifier, actuating devices, power supply source, and additionally introduced integrator amplifier- setter, controlled capacitor and filter. Rectifiers are made with controlled capacity reaction and opposite poles connection and also connected with filter. Capacitive pickup is connected with output of the first rectifier. Input of controlled capacity is connected via amplifier setter to output of integrator whose input is connected with amplifier output to form the circuit of negative feedback. Output of amplifier-setter is also connected with input of proportional actuating device. EFFECT: provision of regulation of textile machine proportional to the value of detected deviation in properties, and capability of detection of various disturbances. 1 dwg |
