Implementation of Slip-Controller for Induction Motor Drive Employing Indirect Matrix Converter

A new scheme to design the proportional integral (PI) type controller for speed control of a constant Volts/Hz (V/F) three phase induction motor drive employing a matrix converter has been presented. An approximate linear model of induction motor operating in constant Volts/Hz scheme is derived and a design example of a slip controller for a three phase motor is presented. Performance of the designed controller is verified with results from simulation using Mat lab
