Apparatus for controlling synchronous motor |
摘要 |
A synchronous motor controller comprises speed control means for calculating an active current reference value on a basis of a deviation of a speed sensed value from a speed reference value of the synchronous motor, three-phase PQ conversion means for calculating an active current value and reactive current value on a basis of an armature current of the synchronous motor and a voltage phase reference value active current control means for calculating a voltage phase compensating value on a basis of a deviation of the active current value from the active current reference value, voltage phase computing means for calculating the voltage phase reference value and polar-coordinate three-phase conversion means for calculating a three-phase voltage reference value on a basis of the voltage phase reference value and a voltage amplitude reference value.
