Description

converting angular magnitudes and expanding the range of variation of convertible angles.

This is achieved by introducing double-pole angle receivers, an amplifier and an executive motor mounted on the same shaft with additional double-pole angle receivers, the inputs of which are connected to the outputs of the corresponding multi-pole angle sensors, into the code for converting angular values into the code. through an additional amplifier is connected to an additional actuator, the output of another additional angle bipolar is to the other input of the crappepi unit.

In the drawing, the diagram of the proposed device.

The device converts the angular values into a code containing multipole sensors 1 11 2 angles, primary 3 n additional 4 and 5 bipolar angle receivers, basic 6 and additional 7 amplifiers, basic 8 n additional 9, dvggateli, unit 10 compared to the reference device I .

The output signals of the multi-pole sensors 1 and 2 angles are proportional to the angular position of m a and p with an electrical reduction coefficient P. These signals are fed to the input of the receivers 4 and 5 angles. The output signal of the receiver is 5 proportional difference

where Ar is the error of sensor 2; AY - error prpemnika 5;

Y - angular position of the receiver 5, goes through the amplifier to the executive engine 9. Under the influence of this error signal, the engine 9 turns the rotor of the pin 5, and with it the rotor of the receiver 4 until it is in position, i.e. at an angle of 7 pP + A | 3 + A - At the same time, the signal U from the output of receiver 4, proportional to the sum

where Aa is the sensor error 1.

At the output of the comparator unit, an AC / C error signal is formed, proportional to the difference

 E - p (+ D) + Yes + D + Af + Ds,

where af is the receiver error 3;

Ф - angular iolol; preampics 3. Under the influence of this error signal, the executive engine 8 turns the rotor of the receiver 3 angles to a consistent position, i.e.

At the output of the reading device 11, a numerical equivalent of L (code) is proportional, proportional to 1: 1

Since for megapolar angle sensors

the number of pairs of poles is usually 64–128, and the values of Aa, Ay, Af are a few minutes (for sine-cosine rotary transformers, selsins), then the numerical equivalent corresponds to the sum

the angular positions of the object aliks with an error not exceeding the unit of angular seconds.

The use of new elements: amplifier, engine n two angle receivers, advantageous

distinguishes the proposed device from the known. The accuracy of converting two angular magnitudes of 1P1 is increased several dozen times, since it becomes possible to use multi-pole angle sensors

and eliminated the methodological error of the formation, characteristic of the prototype.
