In the previous video, we learned:
What a feedback control loop is and how it is constructed. How a process reacts to a change in controller output.
In this video we will learn:
How we can model the process using a First Order Process with Dead Time, or FOPDT, and
The format of the Proportional-Integral-Derivative, or PID control equation.
In the previous video, we learned that the quantity we want to control is measured by a sensor and reported to the control system as the Process Variable.
In this lesson, we will use a heat exchanger as an example, and the Process Variable, or PV, is the exit temperature from the heat exchanger. The range of the Process Variable transmitter is 0 to 400 ° F.
In this video we will learn:
1) How each term of the PID control equation affects a process controller in automatic mode.
2) How the process reaction curve values of “process gain”, “dead time”, and “time constant” can be used to determine the tuning parameters for a PID controller.
