Lambda PID Tuning Tool

A web application for tuning PID controllers in wastewater treatment systems using the step-response (lambda) method.

Features

• Upload process data in CSV format
• Analyze step response characteristics
• Calculate optimal PID parameters
• Support for multiple control system types
• Interactive visualization of results

Getting Started

Prerequisites

• Node.js 16.8 or later
• npm or yarn
