Description

in operation of the device when modeling elements of electrical systems

The goal is achieved by introducing a load element and two switches into the device, the moving contact of the first switch connected to the output of the current controller, the closing contact of the first switch connected to one output of the load element, the other output of which is connected to the output of the current sensor, and disconnect the main contact of the first switch is connected to another output of the device, the movable contact of the second switch is connected to the input of the function converter, the closing contact of the second switch ents connected to one input device, and the normally closed contact of the second switch is coupled to the output of the current sensor. The operation of the device is illustrated in the drawing.

The device contains a current regulator 1, a fuzzy transducer 2, a current sensor 3, a load element 4, switches for two positions 5 and 6 of the driver.

The energy source is connected to the device (clamps 7 and 8), and the consumer is connected to the output of the device (clamps 9 and 10).

The device works as follows

When simulating the SES (power supply), the moving contacts of the switch are closed to the opening contacts. The power supply of the required power is connected to the input of the device, and the real consumer is connected to the output of the device. The output voltage of the source is supplied to current regulator 1, which converts it according to the output signal VM of the function converter. At the same time, the current of the 3c system, defined by the expression, flows through the consumer.
