Didactic platform for DC motor speed and position control in Z-plane

Area of Science:

• Engineering
• Control Systems
• Mechatronics

Background:

• Discrete control theory is fundamental in engineering education.
• Existing didactic platforms can be expensive or limited in scope.
• Practical implementation of controllers like PID is crucial for students.

Purpose of the Study:

• To describe the implementation of an affordable didactic platform for discrete control theory.
• To provide a step-by-step guide for controlling DC motor speed and position.
• To address common practical issues in controller implementation.

Main Methods:

• Development of a low-cost hardware platform.
• Implementation of P, PI, PD, and PID controllers.
• System simulation and comparison with experimental data.

Main Results:

• Successful control of DC motor speed and position demonstrated.
• Commonly overlooked problems and their solutions identified.
• High correlation (ρ=0.983) between simulated and real system behavior.

Conclusions:

• The developed platform effectively teaches discrete control concepts for undergraduate and graduate levels.
• The platform facilitates understanding of DC motor control and PID tuning.
• The study validates the platform's accuracy through simulation-experiment comparison.
