The narrative explores the challenges faced by modern commuters at railway stations, highlighting the struggle against time in a fast-paced environment. It underscores the inconvenience of waiting for various train tickets and the potential benefits of online booking services. However, it also addresses the limitations of these digital solutions, such as connectivity problems and lack of timely updates, which can complicate the ticket purchasing experience for passengers.
An approach to model the current-source-inverter-fed induction motor drive is presented. The mathematical model takes into account the rectifier, inverter, and induction motor dynamics and is established in the stationary reference frame. For controlling the drive speed, a modified indirect field-oriented control is proposed. To counter the effects of torque pulsations at very low speeds and the rotor resistance variation, a slip angle compensation loop is included in the control law formulation. Both computer simulation and simulation results are presented.
