| description | The article describes methods for analyzing dynamic processes
in structures that form a mechanical moment in asynchronous
electric motors with frequency control. For the first time, the
nonlinearity of the mechanical characteristics of an asynchronous
electric motor is taken into account in the transfer function of the
torque former, which is expressed in dependence of this function
on sliding (lag of the rotor speed of rotation of the speed of rotation
of the stator magnetic field) and on the frequency of the voltage at
the motor stator. It is shown how dynamic positive feedback on the
stator current «linearizes» an asynchronous electric drive without violating the stability of transients. This work is an example of
how the initial complicated (but more accurate!) Interpretation of
nonlinearity made it possible to find a new better solution to the
problem of controlling a complex dynamic object. |
