摘要： A control device includes a slip calculator that calculates a first slip frequency of an induction motor, a current detector that detects motor current that passes through the induction motor, an adder that calculates a primary frequency by adding a speed command and a second slip frequency that are given, a command voltage generation unit that generates first command voltage from the primary frequency, a voltage error observer unit that estimates a command voltage error from the first command voltage and the motor current, a slip correction unit that calculates a slip correction amount from the command voltage error, an adder that calculates the second slip frequency by adding the first slip frequency and the slip correction amount, and a voltage error correction unit that corrects the first command voltage using the command voltage error and outputs second command voltage.
