Title:
インバータの制御装置及び制御方法
Document Type and Number:
Japanese Patent JP4085976
Kind Code:
B2
Abstract:
A carrier wave frequency generating unit 9 modulates a frequency f of a carrier wave in a triangular shape. Occurrence of drawbacks due to the frequency f of the carrier wave can thereby be prevented. Because the frequency f of the carrier wave can be easily computed and estimated, a delay time of control, which is due to time for computing the frequency or an integration constant of PID control, can be kept to a minimum, and motor efficiency can be prevented from deteriorating. Because a control delay time can be estimated easily, it is possible to prevent carrying out of delay compensation by feed forward, and to prevent the motor efficiency from deteriorating.
