“…The load torque variation versus cereals flow and the rotational speed versus cereals flow represent the general mechanical model of the cereals mill. The induction motor modelling is widely treated in [17]- [19]. In d-q reference frame rotating, the electric, magnetic and mechanic equations governing the induction motor operating is given by:…”

“…The transfer function of current loop is established by applying the Laplace transform to the electrical equation with the assumption that the converter can be modelled by a static gain G s , which represents the ratio between the output voltage and the modulation voltages, and that the term v g (s) is presented as a perturbation. These assumptions allows to establish the following relationship: According to (19) and (30), the closed loop transfer function of the current is given by:…”

PV/Battery microgrids hold the most promising solution for providing electricity to remote areas. However, the power quality of these microgrids is vulnerable to nonlinear loads and power electronics components, often necessary to power certain systems such as the cereal grinding systems. These grinding systems consist of mills locally designed driven by induction motors. Given the constraints of microgrids and the structure of the cereal grinding system, a single-phase-to-threephase Power Factor Corrector with two control strategies is proposed. The PFC control is used to control the power quality of the microgrid but also to regulate the DC-link voltage. The field oriented control strategy is used to improve the system efficiency. The performance of the power converter and control strategies are evaluated in simulation under Simulink environment. Results have verified the effectiveness of the proposed controls with a low current Total Harmonic Distortion, a near-unity power-factor and a significant efficiency improvement of cereals grinding system.

“…Most researches are based on the Field-Oriented Control and Direct Torque Control, [8][9][10][11][12][13] .Each method presents its respective advantages and disadvantages. Both, Extended Kalman Filter (EKF) [14], and Model Reference Adaptive System (MRAS) [15][16][17][18][19][20], based methods give robust speed and flux estimates but they are complex in implementation. Sliding mode observers [21] is used to estimate rotor flux, rotor time constant and motor speed.…”

Multi -phase ac motor drives are nowadays considered for various applications, due to many advantages that they offer when compared to three-phase motors. Cancellation of mechanical position or speed sensors at the motor shaft have the attractions for adjustable speed drives of induction motor to reduce the cost and increase the reliability. To replace the sensor, information of the rotor speed is extracted from measured stator currents and voltages at motor terminals. This paper investigates speed estimation method using model reference adaptive system (MRAS) to improve the performance of a sensorless vector controller of six-phase induction motor (IM). In the proposed method, the stator current is used as the state variable to estimate the speed. Since the stator current error is represented as a function of the first degree for the error value in the speed estimation, the proposed method provides fast speed estimation and is also, more robust to variations in the stator resistance, compared with other MRAS methods. Consequently, this method can improve the performance of a sensorless vector controller in a low speed region and at zero-speed. The proposed method is verified by simulation using the Matlab/Simulink package. The performance of the proposed system is investigated at different operating conditions. The proposed controller is robust and suitable for high performance six-phase induction motor drives. Simulation results validate the proposed approaches.
