In this paper, a new variable structure position control law for a Six Phase Induction Machine (6PIM) is proposed. The algorithm based on a time-varying switching line guarantees the existence of sliding mode since the beginning of the shaft motion. Indeed, the surface is initially designed to pass through the initial representative point and subsequently moved towards a predetermined desired surface...
A robust position control for induction motors using field oriented control theory is presented. The proposed controller is based on variable structure control and provides global asymptotic position tracking in the presence of unknown parameters and load torque variations. The proposed design incorporates an improved method of flux estimation that operates on the principle of flux and current observer...
This paper, presents a Direct Field-Oriented Control (DFOC) of doubly fed induction machine (DFIM) motor mode with a variable structure control based on a sliding mode control (SMC). Our aim is to make the speed and the flux control robust to parameter variations. The use of the nonlinear sliding mode method provides very good performance for motor operation and robustness of the control law despite...
The design of a speed sensorless PWM robust control scheme for an induction motor drive in order to control the rotor speed is proposed. The proposed design is divided in two parts. In the first one it is designed a speed estimator to estimate the rotor speed. In the second one it is developed the proposed robust control. This robust control comprises two parts, the so called inverse dynamic technique...
The main goal of increasing the number of phases in an induction machine is to ensure its performance in all the operating modes such as normal, disturbed and faulted settings. When the induction machine is working under a faulted mode such as one or more phases are missing, this leads to a high torque oscillations and bad tracking behaviour. Designing a suitable control design such as sliding mode...
