Abstract
In this paper, an indirect field-oriented control (IFOC) induction machine drive
with a conventional PI and sliding mode controllers is presented. The robustness of ac
machine drive speed performance with these controllers is checked in terms of variation
of machine parameters.
The design includes rotor speed estimation from measured stator terminal
voltages and currents. The estimated speed is used as feedback in an indirect vector
control system, such that the speed control is performed without the use of shaft
mounted transducers.
The high performance of the proposed control schemes under load disturbances
is studied via simulation cases. The components of the speed controlled indirect field-oriented
induction machine with the both controllers are simulated using SIMULINK,
while the dynamic of induction machine is simulated using the potential of S-function
block and its attached script file.
