abstract = {This paper presents a hardware implementation of sensorless Backstepping control for induction motor drive. The presented Backstepping control scheme has been designed in the stationary reference frame to reduce the control algorithm complexity. Furthermore, a full order Luenberger observer has been proposed for speed and torque estimation. Several operation conditions of the IM have been conducted such as load application, speed direction reversal and low-speed condition. In addition, an industrial benchmark test which comprises all speed condition has been done to check the control ability in different operation points. This work presents for the first time the experimental implementation of this developed control algorithm. The obtained experimental results prove the effectiveness and performance of the proposed control scheme.},

abstract = {This paper proposes a fault-tolerant control technique against current sensors failure in direct torque controlled induction motors drives. Several important aspects are covered in the proposed algorithm, such as the detection of sensors failure, the isolation of faulty sensors, and the reconfiguration of the control system by a correct estimation. A logic circuit ensures fault detection by analyzing the residual signal between the measured and estimated quantities, while a single modified Luenberger observer performs the task of estimating the line currents, even when all the sensors are in the faulty state. In addition, a decision logic circuit isolates the erroneous signal and simultaneously selects the appropriate estimated current signal. The proposed scheme is tested on MATLAB/Simulink environment and experimentally validated in a laboratory prototype mainly containing a dS1104 card and 4 kW induction motor.},

abstract = {this paper deals with a speed sensor fault tolerant control (FTC) scheme for induction motor (IM) drive based on direct torque control (DTC) and adaptive stator flux observer (ASFO). Many important points are treated in the proposed algorithm, which are the detection of the sensor failure, isolation of the faulty sensor and the reconfiguration of the control system by proper estimation. An adaptive stator flux observer is used instead of classical flux and torque estimator to perform the stator flux components, electromagnetic torque, flux magnitude, rotor position and the estimated rotor speed. Furthermore, a fault detection and isolation (FDI) logic circuitry is used to detect speed sensor fault and isolate it and simultaneously generate a logic impulse to switch to the sensorless mode. The proposed algorithm is simulated in MATLAB/Simulink.},
