Resource Overview
This project demonstrates the design and simulation of a dual closed-loop DC drive system for speed and current regulation using SimPowerSystem in Simulink. The implementation features three-phase bridge rectification with adjustable smoothing reactor Lp values optimized through simulation. The simulation generates dynamic response curves for motor speed, current, and voltage during no-load startup and rated load application at 2.5 seconds, accompanied by theoretical analysis of speed regulation principles through MATLAB's data visualization capabilities.
Detailed Documentation
In this documentation, we will design and simulate a dual closed-loop DC drive system for speed and current regulation using SimPowerSystem within Simulink. The system implementation employs three-phase bridge rectification circuitry, with the smoothing reactor Lp value being optimized based on simulation performance analysis. The model will generate dynamic response curves capturing motor speed, current, and voltage variations during no-load startup conditions and upon application of rated load at 2.5 seconds. Using MATLAB's plotting functions, we will visualize these transients and perform detailed analysis based on speed regulation theory to evaluate system performance characteristics, including controller response times, stability margins, and steady-state accuracy metrics.
