Application of PID Controller in Industrial Machinery Systems
You may have heard about the PID controller, its algorithms, coefficients, and classic examples such as the “water level control” and “temperature oven stabilization.”
But have you ever wondered when to use PID and how it is applied in real-world machinery systems?
Let’s explore this topic with KTV in the following article.
The PID controller operates based on three main components:
Setpoint (desired value), Feedback (measured value), and the PID control loop.
Its fundamental principle is to control an actuator (such as a motor or SSR) so that the feedback value quickly reaches the setpoint with minimal overshoot.
The PID controller is an indispensable tool for stabilizing the operation of any feedback-based control system.
1. Maintaining Stable Water Pressure
- Setpoint: Example: 5 Bar
- Feedback: Measured pipeline pressure
- Control: PID adjusts the speed of the water pump motor

2. Temperature Stabilization in Heating Furnaces
- Setpoint: Target temperature
- Feedback: Temperature measured by PT100 sensor
- Control: PID controls the SSR firing angle to regulate the heating resistor
3. Winding Control for Copper Coil Machines
- Setpoint: Center position of the dancer
- Feedback: Position measured by a distance sensor
- Control: PID adjusts the winding motor speed

4. Tension Control in Steel Rolling Systems
- Setpoint: Desired tension force
- Feedback: Force measured by load cell
- Control: PID regulates motor speed to maintain constant tension

Conclusion
The PID controller is an essential solution in industrial automation.
All Parker drives and controllers such as AC10, AC20, AC30, and DC590 are integrated with PID functionality — helping optimize systems, reduce setup time, and improve precision.
In the next article, KTV will guide you through configuring the PID controller on Parker AC10 for winding applications in the cable industry.
