Client :

Arthur C. Clarke Institute for Modern Technologies

Start Date :

2021

Role :

Research Engineer

Overview

Designed and implemented a PID-based motor speed controller using a Siemens S7-1200 PLC integrated with a Delta VFD and encoder feedback. Developed a WinCC HMI for operator interaction, providing intuitive control and real-time monitoring of motor performance.

Key Contributions

  • Closed-Loop PID Control — Ensures smooth and stable motor speed regulation under varying loads.
  • PLC–VFD Integration — Reliable communication between Siemens S7-1200 and Delta VFD for precise drive control.
  • Encoder Feedback — Real-time speed sensing for accurate loop response.
  • WinCC HMI Interface — User-friendly dashboard for monitoring, control, and parameter tuning.

Applications

Industrial conveyors, machine tools, and automated systems requiring precise closed-loop motor speed control.
