As a DCS engineer, it’s important to understand your PID tuning process. Knowing in advance which steps to take and why to take them is necessary before jumping into the different PID tuning methods available. You’ll be able to get the most out of your PID tuning and ensure that you reach your desired plant performance.
In an industrial plant, tuning PID loops is a time-consuming and difficult job. To achieve optimal results, it’s essential to prevent the PID loops to oscillate or overshoot. However, finding the ideal set of parameters for each specific situation is almost an art — it requires experience.
There are many different methods to tune your PID loops; trial and error, Ziegler-Nichols, Cohen-Coon, or model-based PID tuning using software. If you focus on understanding the PID tuning process instead of just using your gut-feeling, you provide more added value to your plant operations.
In this ebook, we will unpack what PID tuning is, how to use it, and how it contributes to optimal plant performance.
