    Virtual laboratory platform for enhancing undergraduate level induction motor course using MATLAB/Simulink
    (2012) Syal, A.; Gaurav, K.; Moger, T.
    With the advent of various simulation software packages and low cost personal computing devices in the market, computer-aided teaching tools have become an important part of present pedagogy. These tools support the classroom teaching by enabling the instructor to illustrate the working of various systems by means of computer generated graphics. This paper presents a very easy and interactive model based on computer simulation in MATLAB/Simulink to simulate the no load test, load test and blocked rotor test on 3-phase slip ring and squirrel cage induction motors. The well known equivalent circuit model along with the torque equation is used to model the motor without considering the effects of magnetic saturation. The simulation environment plots all relevant graphs including circle diagram of the given motor, thus acting as a complete graphical teaching aid for the induction machine course at undergraduate level. This model facilitates learning especially for the students pursuing a distance-learning/correspondence course which does not provide them with the laboratory facilities. © 2012 IEEE.

    Experimental, simulation and a case study on electrical energy consumption in mine drive haulage system
    (Institute of Electrical and Electronics Engineers Inc., 2015) Moger, G.D.; Murthy, C.S.N.; Yaragatti, R.Y.
    The experimental investigation study on energy consumption of fabricated 3hp mine drive haulage system is presented. The performance analysis of energy consumption based on existing mine drive haulage system of underground coal mine and experimental set-up is prepared in the laboratory for a 3-hp wound rotor induction motor. The experimental and a case study results are simulated using MATLAB /simulink model and the compared results are presented in this paper. © 2015 IEEE.

    Simulink-Based Comparative Study and Selection of a Controller for a Waist-Assistive Exoskeleton
    (Springer Science and Business Media Deutschland GmbH, 2024) Thomas, M.J.; Mohanta, J.; Sahoo, S.; Santhakumar, S.
    This paper describes the conceptual design and comparative simulation study of three controller strategies—Proportional Integral Derivative (PID), PD-based Computed Torque Control and PD-based Sliding Mode Control (SMC) for a waist-assistive exoskeleton. The exoskeleton is modelled in Simulink, and its joint control is simulated for a predefined desired trajectory. The motor, joint and link parameters are incorporated into the Simulink model to match the properties and evaluate the performance similar to the real-time system. In addition, MSC ADAMS-based simulation study is also performed to validate the dynamic model of the exoskeleton. The preliminary study indicates that the SMC controller shows better tracking accuracy than the other two strategies. The proposed exoskeleton is designed to reduce the effort taken by the user during regular sit-to-stand and weight-lifting operations. It is intended to lower the strain the lumbar muscles take during standing and lifting operations over the long run. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

    Methodology for Modelling a Custom SRM Configuration Using MATLAB/Simulink
    (Institute of Electrical and Electronics Engineers Inc., 2024) Jose, N.; Jayaraman, A.; Bhaktha, S.; Sarma, S.; Balasubramanian, B.; Gangadharan, K.V.
    Switched Reluctance Motors (SRMs) have gained significant attention in recent years due to their simplicity, robustness, and energy efficiency, making them suitable for various applications such as electric vehicles. However, the development of custom configurations for SRMs presents challenges due to limited options in existing simulation platforms like MATLAB/Simulink. This paper presents a comprehensive methodology for modelling and simulating a custom SRM configuration, specifically a 4-phase, 8/18 Multi-Teeth (MT) SRM, using MATLAB/Simulink. The methodology involves estimating Look-Up Tables (LUTs) using electromagnetic static Finite Element Analysis (FEA), developing mathematical models for phase current and torque, and integrating them into a Simulink model. After that, a closed loop speed control simulation using Hysteresis Current Control (HCC) and Anti-windup PID is applied to the created model. The simulation results demonstrate the effectiveness of the proposed methodology in accurately predicting the motor's performance. Additionally, a comparison with FEA results highlights the model's ability to closely replicate real-world behaviour, despite minor discrepancies attributed to differences in handling mutual phase coupling effects. © 2024 IEEE.
