Real-Time PID Controller and Graphical Interface

This repository contains a real-time control system for a PID (Proportional, Integral, Derivative) controller with a graphical user interface (GUI). The system leverages an Arduino-based hardware setup for process control and a Python application using PyQt5 and pyqtgraph for visualization and interaction.

Key Features:

• PID Control: Fine-tune your system with real-time PID parameter adjustments.
• Serial Communication: Communicates with Arduino over a serial connection to apply control commands and read sensor data.
• Graphical Visualization: Real-time plotting of system variables such as target vs. actual position, error values, and PID contributions.
• User Interaction: Update target values and PID parameters on-the-fly through an intuitive GUI.
• Anti-Windup Handling: Toggle anti-windup feature from the interface to prevent integral term saturation.

Ideal for educational purposes, hobbyists, or as a starting point for more complex control systems.

Scheme

The scheme of the project is shown below:

in this case a L298N is utilized but any motor controler is enough.
