Abstract: FIELD: electrical engineering. 
     SUBSTANCE: invention relates to electrical engineering and is intended for use in industrial drives with squirrel-cage induction motors. Control device is realized using the principle of subordinate adjustment of coordinates. Main feedback is closed by voltage on stator winding of asynchronous motor (12) by means of serially connected voltage sensor (13) and measuring transducer of active value of voltage (14). Setting of voltage on stator winding of asynchronous motor is performed by means of setter (14). Voltage regulator (10) performs the mismatch signal conversion in accordance with the standard regulation law, for example proportional or proportional integral. Output signal of voltage regulator (10) acts at input of current limiting unit (9), which provides limiting the setting signal for current controller (6) corresponding to the current of the power supply allowed during the specified time interval. Subordinate current control loop is arranged with the help of current sensor (7), root-mean-square current converter (8) and current controller (6) implementing the standard control law. Asynchronous motor (12) active power control circuit is arranged by means of active power transducer (4) and active power controller (1) implementing the standard control law. Output signal of active power controller (1) operates at input of pulse-phase control unit (2), which generates pulses for thyristor regulator (5). As a result of three feedbacks, the actual voltage value at the output of thyristor regulator (5) during start-up is always maintained so that the current does not exceed the level set by the current limiting unit (9), and the active power does not exceed the value set by the active power limitation unit (3). Thus, during start-up of the asynchronous motor, active power consumed from the power supply does not exceed the specified value. 
     EFFECT: technical result consists in improvement of efficiency of power supply source energy source usage.

Abstract: FIELD: measuring equipment.  
     SUBSTANCE: invention relates to measuring equipment and in particular to methods and systems for checking the accuracy of measuring distances using laser rangefinders. According to the proposed control method, a program is loaded into a computer containing the calculated true values ​​of the distance from the lens of the output channel of the rangefinder to the target and back, as a function of the time the light beam travels to the target and back, at the luminous flux power required to overcome this distance with minimal scattering. The computer forms a database necessary to compare the true values ​​of the distances to the target with similar indicators obtained using the control system, which determines the accuracy of the rangefinder. In the control system, with the help of mechanisms 7 and 8 installed on the optical bench 6, the optical axes of the range finder 1 and the optical system 9 are adjusted. The light signal emanating from the lens 2 of the range finder is attenuated in the attenuator 13 and through the fiber optic bundle 14 enters the photodetector the electronic unit 16 delaying the secondary pulse connected to the computer 5. After that the computer gives a command and the laser emitter 10 generates a light pulse of the required parameters which is calibrated in terms of the amplitude to the equivalent power parameters of the initial pulse of the rangefinder in the optical scheme 11 and is transmitted to the output lens 12 of the optical system, and after that it is sent to the receiving lens 3 of the rangefinder and to the computer. 
     EFFECT: system can be suitable for monitoring the accuracy of any laser rangefinder in which the range is determined by the time it takes a light pulse from the rangefinder to the observed object and from the object to the device.
