Using the DQ model of Induction motor, the induction motor drive system, in which slip controls the stator current, is designed and analyzed.
Discussions are made also on the effects of the gains in the control loop and the filter in the DC-link on transient speed response. A method of linear control of the average rectifier output voltage is suggested, and the difficulties in the tachogenerator and the operation of CCI in the rejenerative mode are discussed.
