SYSTEM FOR STABILISING TORQUE OF POWERED GYROSTABILISERS Russian patent published in 2010 - IPC G01C21/00 

FIELD: physics; navigation.

SUBSTANCE: invention relates to design of navigation system devices and can be used for controlling asynchronous motors of powered gyrostabilisers with variable kinetic momentum, particularly used in positioning systems of artificial earth satellites. To achieve the given result, the required moment on the shaft of an asynchronous motor of a flywheel - parametres of stator phase currents are formed depending on signals of the active and reactive components of the stator winding of the asynchronous motor, basic parametres of the rotor circuit of the motor and rotation speed of its rotor. There is no need to use a driving generator with program-varied frequency and a frequency adder unit. The proposed set of features allows for sufficiently high stability of absolute slip and, consequently, of speed and torque of the motor.

EFFECT: simplification of system and increased reliability.
