    Mathematical Model Implementation of SPWM fed Three-phase Induction Motor Drive Using MATLAB Simulink
    (Intelligent Automotive Systems Research Cluster, Electrical Electronic and Automation Section, University Kuala Lumpur Malaysian Spanish Institute, Kulim, 09000, Kedah, Malaysia*, 2020) Amir Rasyadan; Sazali bin Yaacob; Pranesh Krishnan
    Three-phase induction motors are used in a vast area of applications mainly due to their simplicity, ruggedness and high reliability. With recent advancement in semiconductor technologies, the use of fixed speed induction motor drive is becoming obsolete, majority of the applications now requires inverter-based drives for variable speed operation. In the study of induction motor drive operation, mathematical models are often used to simulate the steady state and transient behavior of induction motor. However, to develop such model is not a straightforward task. Knowing only the equations by themselves are not always enough without some knowledge on solving mathematical equations with the use of computer simulation software. This work presents an approach to implement the mathematical model of a Sinusoidal Pulse Width Modulation (SPWM) fed three-phase induction motor drive in MATLAB Simulink. The sub models include induction motor DQ model and a voltage source inverter (VSI) fed by SPWM signal generator. The presented model implementation is able to simulate the dynamic behavior of an induction motor operation, this would be useful for further studies on the development of induction motor drive system.

    Simulation Analysis for Induction Motor Drive Fault Detection and Localization Under Variable Load and Speed Operation
    (IOP Publishing Ltd, 2021) Sazali Yaacob; Amir Rasyadan; Pranesh Krishnan
    The induction motors are widely used in the industry for their advantage of being reliable, rugged, and simple in construction. Nonetheless, the use of inverter-based drives has increased the overall system failure possibility mainly because of the power electronics switches used in the inverter itself. For that reason, it is crucial to monitor the inverter switches health during operation to avoid total system breakdown. A method to do so is by using the current vector trajectory analysis on the induction motor stator current signal. However, one disadvantage of using this method is that it is negatively affected by the load and speed variations. This paper is intended to discuss further on the matter and look into the methods that can be used to minimize the effects associated with the load and speed variations using computer simulation analysis.

    Simulation of SPWM Fed Three-phase Induction Motor Drive Mathematical Model Using MATLAB Simulink
    (2020) Amir Rasyadan; Sazali bin Yaacob; Pranesh Krishnan; Mohamed Rizon; Chun Kit Ang
    Three-phase induction motors are used in a vast area of applications mainly due to their simplicity, ruggedness and high reliability. With recent advancement in semiconductor technologies, the use of fixed speed induction motor drive is becoming obsolete, majority of the applications now requires inverter-based drives for variable speed operation. In the study of induction motor drive operation, mathematical models are often used to simulate the steady state and transient behavior of induction motor. However, developing such models are not as simple. One must develop the understanding of the mathematical equations to be used and also having the knowledge to solve the equations with the use of computer simulation software. To address this issue, this work presents an approach to implement the mathematical model of a Sinusoidal Pulse Width Modulation (SPWM) fed three-phase induction motor drive in MATLAB Simulink. The sub models include induction motor direct quadraturemodel and a voltage source inverter fed by SPWM signal generator. The presented model implementation is able to simulate the dynamic behavior of an induction motor operation, this mathematical model implementation would be useful for further studies on the development of induction motor drive system.
