“…Precise control of LIM parameters, including speed and thrust force, is given, verified by the simulation results. In most applications related to control machine drives, transient response analysis of the electrical machines is critical, and a dynamic d-q model is developed for this purpose [14]. The d-q model of the equivalent electrical circuit, considering end effects, is used to present the dynamics for LIM and complete steps to develop the dynamic model are represented in Fig.…”

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.
