| Abstract |
This paper presents an original control strategy for
Doubly Fed Induction Machine (DFIM) which both stator and
rotor circuits are connected to Voltage Source Inverters (VSI).
This configuration reduces the power converters size. In the
proposed system model, we consider the flux as state variables
and no more the currents. As a Direct Torque Control strategy,
instead of using PWM linked with an equivalent nonlinear control
method, we proposed to apply a Variable Structure Control
(VSC) strategy with adapted switching tables to regulate the
fluxes and the electromagnetic torque. Transient and steady states
behaviour are validated by ”SABER” software simulations where
all digital control is implemented in C language and introduced in
SABER environment. This quasi-experimental methology allows
to verify the system working in real operating conditions |
