Simulink Simulation Model for Dual Closed-Loop Control of DC Motor

This experiment presents a Simulink simulation model for dual closed-loop control of DC motors. We begin by examining the fundamental principles and operational mechanisms of DC motors, including mathematical modeling using transfer functions and state-space representations. The discussion then progresses to closed-loop control system concepts, covering both feedback loops (current and speed control) and feedforward compensation techniques. The model construction process in Simulink is demonstrated step-by-step, including input signal configuration using Signal Builder blocks, PID controller design through Transfer Function blocks, and parameter tuning using Optimization tools. Key implementation aspects include current loop stabilization using proportional-integral controllers and speed regulation through cascade control architecture. The simulation phase involves performance evaluation through scope outputs and data logging, analyzing transient response characteristics and steady-state accuracy. Through this experiment, participants will gain comprehensive understanding of dual closed-loop control principles for DC motors and master practical Simulink simulation techniques for motion control applications.
