| Abstract |
An approach to discrete-time sliding-mode (SM)
current control and conventional SM with smoothing filter
is presented for field-oriented induction motor (IM) drives.
Design of both proposed SM controllers is based on space
vector PWM scheme by introducing some parts of the stator
model as control input, which may correspond to voltage
vector command. The control input was obtained employing
the error between measured and reference currents of the
stator. In order to compare the performance of proposed
two SM current controllers with each other and with a
conventional PI controller, they were simulated and also
experimentally implemented for the indirect field oriented
drives of an IM. The results verified to validity of proposed
both SM current controllers and superiority of discrete time
SM controller to conventional PI controller and SM with
low pass filter (LPF). |
