Objectives
1.Help students grasp the practical use of feedback control theory through hands-on experiments with real-world tools.
2.Simplify mathematical concepts.
3.Incorporate tangible hardware components.
4.Introduce advanced methodology, specifically Model-Based Design (MBD).
5.Explore web-based control.
6.Minimize the emphasis on complex mathematics and programming.
Project Overview
In this project-based learning tutorial, undergraduate students will learn about feedback control systems using an RC circuit as a plant model. The tutorial will guide students through the process of developing a mathematical model of the RC circuit, simulating the plant and controller models using Simulink, designing a PID controller using root locus and frequency domain methods, and implementing the control system using Waijung 2 for ESP32. Students will also learn about Model-Based Design (MBD), hardware-in-the-loop (HIL) testing, and creating a standalone model with a web interface to adjust PID gains and display time-series responses.
