SYSTEM CONTROLLING MACHINE OF DUAL POWER SUPPLY Russian patent published in 1998 - IPC

FIELD: electrical engineering. SUBSTANCE: invention may be used for design of modelling stands with high dynamic properties. In system of controlling machine of dual power supply the latter is connected in sequence through current pickup of rotor 2 to outputs of frequency converter 3. It has tachogenerator 4 and rotary transformer 5 put on shaft which outputs are connected in series through demodulator 6 to controlling inputs of coordinate converters 7 and 8, current pickup of stator 9, voltage pickup 10 of stator, coordinate converters 11 and 12 connected in series through trigonometric analyzer 13 to analog inputs of phaser 14 which outputs are connected to inputs of phase converter 13, adders 16 and 17 connected with their outputs to controlling inputs of correction unit 18 of orienting vector, correcting device 19, adder 20 connected in series through flux regulator 21 to first input of adder 22 which second input is connected to output of correcting device 23, adder 24 connected in series through current regulator 25 to output of adder. EFFECT: increased accuracy of control of electromagnetic moment thanks to linearity of channels controlling electromagnet moment. 3 dwg
