Literature review reveals challenges and advancements in controlling dc motors using converters, suggesting improvements in speed regulation.
Motor speed control is essential in various industrial and domestic applications, where efficient techniques enhance performance, reduce energy consumption, and minimize harmonic distortions. This literature review examines recent advancements in controlling DC, induction, and brushless DC (BLDC) motors using converters such as full-bridge cycloconverters, phase-shifted full-bridge converters, and thyristor rectifiers. Key studies focus on transfer function-based estimation, PID controllers, voltage control methods, and harmonic analysis. The review highlights the shift toward digital and predictive controls for improved dynamic response and reduced total harmonic distortion (THD). Findings indicate that converter-based strategies offer flexibility in speed regulation, though challenges like parametric variations and load changes persist
