Adaptive Sliding-Mode Control of a two five-phase series-connected induction motors drive

In this paper an effective direct torque control (DTC) and stator flux control is developed for a two five-phase induction motors (IMs) drive with sinusoidally distributed windings. Combining the sliding-mode (SM) control and adaptive input-output feedback linearization, a nonlinear controller is designed for each motor, which is capable of tracking control of the stator flux and torque independently. The motor controllers are designed separately in order to track a desire second order linear reference model in spite of motor resistances mismatching. The effectiveness and capability of the proposed method is shown by computer simulation.
