Loop Problem Signatures series

 

 

Introduction to "Loop Problem Signature" series

 

Over the years I have had many requests to write a book and give more detailed explanations of some of the problems we have encountered in our work on practical loop optimisation. However,  I believe that people learn far more, and even more importantly, would gain much better understanding of the subject by actually attending our courses where things are demonstrated by doing exercises on a powerful simulation package, rather than trying to read it up in a book.  But since some of the past delegates did not have the time and/or opportunity to practice what they had learnt in their plants, and soon forgot much of the course, many of them have also requested me to put out a book or CD.

 

Series 1. Basic Troubleshooting and Loop Tuning

 

I have therefore published some of the information dealt with in our courses on a PDF Series. Michael Brown's Basic Troubleshooting and Loop Tuning Course consists of 31 chapters, and is a new and very practical approach to the basics of regulatory control loop optimisation. Some of the chapters are included below in the Loop Problem Signatures series. If you would like to buy the complete course, please contact Michael Brown Control Engineering for prices and ordering information.
