Device for adjusting the gain factor of automatic control systems

This device is used to create automatic tuners for automatic control systems, and, with certain modifications, self-tuning systems. This device includes a circuit for isolating the phase of the reference signal, a test signal sensor connected to its input, and two relays whose windings are connected to the outputs of the circuits for isolating the phase of the reference signal and the error signal, respectively. Their outputs are connected to the shaper, which is connected to the servomotor. The test signal sensor is equipped with a rotating transformer which is connected to the motor through a reducer. Here the rotor winding of the rotating transformer is connected to the input of the device, while one of its ends is also connected to the output of the sensor.
