MATLAB/Simulink Simulation of Dual-Loop Speed Regulation System for DC Motors

The following presents a MATLAB/Simulink simulation program for a dual-loop speed regulation system of DC motors, which serves as a fundamental tool frequently employed in graduation projects for Electrical Engineering and Automation majors. This simulation enables modeling and analysis of DC motor dual-loop speed control systems, facilitating deeper understanding and application of motor control principles. The implementation typically includes two PI controllers - an inner current loop regulator and an outer speed loop controller - that work together to maintain stable motor operation under varying load conditions. Through modification and optimization of the simulation parameters, users can explore various motor speed control algorithms and their improvements, thereby enhancing the performance and stability of motor systems. Key simulation components include PWM generation modules, DC motor mathematical models, and feedback sensor implementations that realistically represent actual system behavior. The simulation allows testing of different control strategies by adjusting PI parameters, load torque variations, and reference speed profiles. In summary, this simulation program represents an indispensable tool for electrical engineering graduation projects, providing a practical platform for validating control theories and developing advanced motor control strategies through hands-on MATLAB/Simulink implementation.
