Do CLPM Solutions Adapt to Changing Performance Expectations?
What have you done for me lately? That question directly influences the behavior of most everyone within a production facility. Face it, we operate in a meritocracy that has little
Does Tuning a PID Controller Require a Bump Test?
It's generally accepted that tuning a PID controller requires some form of testing. Whether a step, bump, doublet, or pseudo random binary sequence, the test forces a change to the
What Tuning Software is Available for Use With Rockwell Automation Controllers?
If you're tired of manual tuning and you want more than the auto-tune function can muster, then you're in luck. There are a variety of software products that support the
What is Model-Predictive Control?
Model-Predictive Control (MPC) is advanced technology that optimizes the control and performance of business-critical production processes. So is Control Loop Performance Monitoring (CLPM) software. But if both help practitioners to
What Is Cascade Control? How Is Cascade Control Configured?
As they say: Timing is everything. The lag between upset and response directly impacts a system's performance along with the performance of other processes with which it interacts. Fortunately, there
What is Lambda Tuning?
Tuning a PID controller should always start with a clear understanding of both the control objective and the Design Level of Operation (DLO). Unfortunately a subsequent step (the calculation of
What is Variance? What Metrics are Useful in Identifying Process Change?
Ever walk onto the production floor and just sense that something was different? Whether it was something you saw, heard or even felt, a certain sixth sense kicked in and
What is Cross-Correlation?
Do you remember when school kids simply lined up according to height before heading to the library or to gym class? Shortest in the front. Tallest in the back. A
What Training is Available for Process Control and PID Controller Tuning?
The latest report published by the Manufacturing Institute underscores the growing shortage of skilled labor here in the United States. Their 2014 study of skills and training Out of Inventory simply affirms
How Do I Isolate the Root-Cause of Control Loop Performance Issues?
Finding controller performance issues in a typical production facility is not hard, but isolating and correcting their root-cause can present real challenges. Ask around stories abound of production staff who
