The Benefits of Feed Forward Control

By nature most people are reactive when it comes to dealing with life’s big expenditures.  Think of happy occasions such as graduations and weddings.  Then consider more somber milestones like retirement.  By most accounts the average worker is wholly unprepared [...]

What is Feed Forward Control?

To no practitioner’s surprise, process control exists as a discipline because manufacturing is complex.  It’s erratic and occasionally unpredictable.  At many facilities it is highly hazardous.  Variability – whether localized to a single process or reverberated throughout a plant [...]

Pros and Cons of Higher Order Models

Modeling is a time-tested approach for decoding a process’ dynamic behavior.  By understanding how a process responds to change it’s possible to apply an appropriate and timely counter measure.  Two common applications of modeling are 1) PID controller tuning, [...]

The Pros and Cons of Cascade Control

As shared previously Cascade Control is an advanced application of Single Loop Control.  Through the use of a secondary and faster PID control loop, practitioners can improve a given process’ ability to correct for known disturbances.  Although it is [...]

Overview of Cascade Control

While Cascade Control is generally considered an advanced control strategy, it is only marginally more complex to implement than Single Loop Control.  More often than not it is applied to improve the performance of a slow process such as [...]
