Abstract
Permanent Magnet Direct Current (PMDC) machines are heavily utilized across the modern industrial landscape, largely favoured for their exceptional torque linearity and mechanical dependability in automation and robotic assemblies. However, ensuring stable velocity regulation when exposed to sudden dynamic load shifts remains a critical engineering challenge. This manuscript delivers an extensive comparative assessment of a PMDC motor driven by a DC-DC buck chopper, evaluating two distinctly divergent regulatory paradigms: a traditional Proportional-Integral (PI) feedback loop and an intelligent Fuzzy Logic Controller (FLC). Utilizing the MATLAB/Simulink environment for rigorous parametrization and waveform analysis, the empirical evidence demonstrates that linguistic rule-based control successfully neutralizes the severe transient oscillations and current surges inherent to rigid PI algorithms. Ultimately, the FLC provides a critically damped, accelerated, and structurally secure response, proving vastly superior for non-linear electromechanical drives.
