Summary: This research presents a sensorless speed control method for a three-phase induction motor using an extended Kalman filter (EKF). A fractional-order-based PID control scheme is proposed to reduce the ripple magnitude in torque compared to using a PID controller. Simulation results show that the fractional order control ensures 20 times faster tracking and reduces the torque ripple magnitude by a factor of 50% compared to PID control, demonstrating the effectiveness of the proposed strategy.

Summary: This paper presents a medium-voltage drive system based on an open-end winding induction machine and a multilevel power converter topology. The power converter consists of cascaded two-level three-phase voltage source inverters connected to each side of the machine windings. A closed-loop model predictive control (MPC) strategy is proposed to simplify the control of the power switches of the inverter. The advantage of reducing the common-mode voltage offered by the open-end winding configuration is fully exploited in this work. The simulation results validate the performance of the proposed topology and control method.

Summary: Finite Set Model Predictive Control (FS-MPC) is commonly used in power electronic converter applications. However, selecting appropriate weighting factors is a challenge, and an alternative approach is to consider cost functions without weighting factors, as done in Sequential Model Predictive Control (SMPC).

Summary: This paper presents a robust and effective method for direct torque and rotor flux control (DTRFC) strategy in an induction motor (IM). The method eliminates uncontrollable angles (UCAs) across the entire speed range. By analyzing the behavior of the DTRFC algorithm, it was found that the basic scheme had UCAs at medium and high speeds. Therefore, a special strategy with 18 sub-sectors (SSs) for medium and high speeds was proposed, while maintaining the basic 6 sectors strategy for low speed. Simulation results using MATLAB/Simulink and experimental verification using a dSPACE-based induction motor DTRFC drive system were conducted to validate the proposed method.

The proposed control method reduces the power ripples and current distortion, and improves the current quality compared to the conventional direct power control scheme. It achieves a high current quality, reduces steady-state errors, and improves the response dynamic of the generator.

Summary: Direct Torque Control (DTC) offers an optimal solution for controlling the behaviors of alternative motors, but speed overshoots, fluxes, and torque ripples remain challenges. The lack of robustness of the PID controller in nonlinear systems has led to the application of optimization algorithms to adjust its parameters. This approach has been shown to enhance system performance in the presence of nonlinearity.

Summary: The direct matrix converter (DMC) is a popular power converter topology option for electric motor drives in industrial applications and critical size and weight applications, such as the aerospace industry. Various control techniques have been developed to exploit the benefits of DMC, including field-oriented control, direct torque control, model predictive control, and sliding mode control. However, sliding mode control suffers from chattering, which can be resolved using the exponential reaching law (ERL) solution. The proposed method was validated through simulation and experimental tests on a three-phase induction machine.
