“…The final block diagram of the induction motor drive is completed by integrating the subsystems in which the torque-current feedback loop and induced emf feedback loop are overlapped. Block-diagram reduction techniques are used to overcome this overlap in which the inner current loop is made independent of the motor mechanical transfer function, and this method offers a simpler construction of the current controller [29][30][31][32].…”

Vector control schemes have recently been used to drive linear induction motors (LIM) in high-performance applications. This trend promotes the development of precise and efficient control schemes for individual motors. This research aims to present a novel framework for speed and thrust force control of LIM using space vector pulse width modulation (SVPWM) inverters. The framework under consideration is developed in four stages. To begin, MATLAB Simulink was used to develop a detailed mathematical and electromechanical dynamic model. The research presents a modified SVPWM inverter control scheme. By tuning the proportional-integral (PI) controller with a transfer function, optimized values for the PI controller are derived. All the subsystems mentioned above are integrated to create a robust simulation of the LIM's precise speed and thrust force control scheme. The reference speed values were chosen to evaluate the performance of the respective system, and the developed system's response was verified using various data sets. For the low-speed range, a reference value of 10 m/s is used, while a reference value of 100 m/s is used for the high-speed range. The speed output response indicates that the motor reached reference speed in a matter of seconds, as the delay time is between 8 and 10 s. The maximum amplitude of thrust achieved is less than 400 N, demonstrating the controller's capability to control a high-speed LIM with minimal thrust ripple. Due to the controlled speed range, the developed system is highly recommended for low-speed and high-speed and heavy-duty traction applications.

“…The stator voltage equations can be reformed for the vector control scheme by using the following relationship in Eqs. ( 28 (31) where σ is the leakage coefficient. The flux-producing element of the stator current is fixed in steady state condition, which is the d axis stator current in the synchronous frames.…”

In this study have been utilized a modified version of ant colony optimization to improve the thresholds of neural networks and weights by including therank-weight approach. Furthermore, this technique easily overcome the drawbacks speed up convergence into the minimum while training the backpropagation neural network. The improved ant colony optimization-backpropagation neural.not only has the capacity to map extensively, but it also enhances operating efficiency noticeably, according to the simulation findings. The simulation results revealed that the speed sensor replaced with the ant colony optimization rw-optimized back propagation neural network-speed identification and motor’s speed determined using this approach the result is satisfactory.

“…Several research studies have been conducted to reduce or eliminate CMV. These studies include the use of advanced inverter topologies [13]- [15], filters [16] or specific modulation techniques [17], [18]. Some modulation techniques allow for reducing CMV without employing filters or advanced converter topologies, thus reducing costs and design time.…”

This paper proposes and studies different sigma-delta (Σ∆) modulation strategies for obtaining a constant common-mode voltage (CMV) by eliminating the CMV level transitions in a five-phase voltage source inverter (VSI). These techniques are based on choosing vectors that generate a constant CMV with values of 0.1V dc or -0.1V dc . Because of the high-switching frequencies used with widebandgap semiconductors, pulse-width modulation (PWM) techniques continually generate high dv/dt values. Therefore, the proposal to combine a Σ∆ modulation strategy with vector selections achieves: 1) a constant CMV level due to the elimination of its level transitions; 2) a reduction in conducted electromagnetic interference; and 3) a high-efficiency converter operation. The average number of switching per transistor of the VSI is analyzed using the results from Matlab/Simulink and PLECS simulations. Experimental results are obtained by applying the proposed Σ∆ modulation strategies on a VSI with silicon carbide (SiC) MOSFETs. The results demonstrate the achievement of the aforementioned features.
