PID Controller Overview

This tutorial demonstrates how a Proportional Integral-Derivative (PID) controller works through controller module using Creo Flow Analysis. The objective of mixing pipe flow model simulation is to determine the flow rate of hot fluid, to attain the desired outlet temperature of 39 °C. The following figure shows the geometry and conditions for the mixing pipe-PID controller simulation.
