Abstract
Progress in the fields of power electronics and microelectronics has made it possible to realize high-performance control-techniques for a.c. machines. Vector control is such a technique with which it is possible to operate a.c. machines with dynamic performance comparable to that of d.c. machines. Among various vector controlled a.c. machines, squirrel-cage induction machine is of particular interest because of its ruggedness and low cost.
In this work, transient and steady-state performance of vector-controlled induction motor drive is investigated by digital simulation. The drive is realised with a 3-phase,4-pole,1.5 hp squirrel-cage induction motor fed by IGBT-based current-controlled PWM voltage-source inverter. Indirect rotor-flux oriented control-scheme is implemented using MCS-80C196KC microcontroller. Four-quadrant operation of the drive is presented.
