| Abstract |
The range of controlled electrical drives is greatly expanded by the transition to A.C. motors. Control
in a moving reference frame, such as field orientation, presents a unifying principle for the design of
high dynamic performance drives. The main problem of the vector control in the field co-ordinates of
motor is the separation of torque and flux control circuits without mutually influencing. For this
purpose the knowledge of the value and position of the rotor flux vector is necessary. Parameters of
the machine are not constant. Especially the stator and rotor resistances are varied in dependence on
the changing temperature of the motor. In this paper is presented the rotor time constant adaptation
method. |
