PID Controller
Controller module in Creo Flow Analysis works as a PID controller. PID controller is used in industrial control applications to regulate flow, pressure, temperature, speed, power and other process variables. This works as feedback-based control mechanism to require modulated control of a component or system. It applies a responsive correction to a control function to achieve the desired output. For example, PID controller is used to maintain the desired speed by increasing or decreasing the power output of the engine, when a car is on cruise control mode.
In this section, the parameters and settings of controller module in Creo Flow Analysis are discussed in detail.
To activate the Controller module:
1. Click
