Abstract
|
This research focuses on the integration of Direct Torque Control (DTC) with multilevel inverters and the implementation of Model Reference Adaptive System (MRAS) for sensorless control in electric motor drives. The study addresses the drawbacks of DTC, such as torque and flux ripples, by proposing an advanced system that significantly reduces these issues and enhances current harmonics. The incorporation of multilevel inverters aims to improve voltage waveform quality and overall system performance. Additionally, the use of MRAS for sensorless control eliminates the need for physical sensors, reducing costs and enhancing system reliability. The research goals include optimizing torque and flux control precision, investigating the impact of multilevel inverters, and advancing sensorless control strategies within the DTC framework. The proposed research methodology involves literature review, simulation studies using MATLAB/Simulink, and comparative analyses to highlight the innovations and advantages of the proposed integration. Ultimately, the research aims to contribute to more efficient and reliable electric motor drives across various applications.
