Fuzzy control of integrated current controlled converter-inverterfed cage induction motor drive

摘要

The paper presents the performance analysis of a vector controlledcage induction motor drive. The drive is fed from a current controlledconverter-inverter system. The switching technique being used in thecontrol of the converter as well as inverter is PWM current control.Closed loop control of the cage induction motor utilizes the fuzzy PIDspeed controller. Advantages offered by the current controlconverter-inverter link are exploited. In order to examine the dynamicperformance of the drive system its model is simulated and results areanalyzed. The potential applications of this particular drive system areoutlined
