Conditions
Payment for courses in our training centre: Required three weeks prior to the course. Payment after this will result in a 5% increase in quoted prices.
Payment for courses in the client’s plant: before or at time of presentation of course.
Original invoices: If e-mailed invoices are not acceptable, then an additional charge will be levied for courier delivery, as normal post is too unreliable.
Accommodation: course participants are responsible for making their own reservations; hotels will be suggested on request.
Cancellations: bookings for all courses cancelled between 21 and 10 days prior to the course are subject to a 50% cancellation fee. Cancellations 10 or less days prior to the course are subject to a 100% cancellation fee. We also reserve the right to cancel any course if an insufficient number of delegates have booked. In such an event, fees that have been paid will be refunded in full. The client is liable for any unrecoverable expenses prepaid by ourselves, or penalties incurred by cancellation of bookings, irrespective of when the client cancelled the booking/s.
Loop signature Part 2-4: Feedforward Control: Part 3 Michael Brown Control Engineering
Editor's Choice Fieldbus & Industrial Networking
In the previous articles in this series, the basic theory behind feedforward control was discussed, and it was also shown how to apply feedforward in practice. In this article, it will be shown how well feedforward can work in practice by giving a couple of examples.

Feedforward control tuning is not nearly as critical as feedback tuning, and fairly simple models are usually fine for the purpose in hand.

Fieldbus & Industrial Networking
Feedforward control is a powerful technique that can dramatically improve control variance in cases where load changes cause big deviations from setpoint and the actual process dynamics are too slow to allow the feedback controller to operate fast enough to catch these disturbances.

Fieldbus & Industrial Networking
The previous series of loop signature articles dealt with the basics of control loop optimisation, and concentrated on troubleshooting and ‘SWAG’ tuning of simple processes. In this new series, consideration will be given to dealing practically with more difficult issues like interactive processes, and with processes with much more complex dynamics.

Fieldbus & Industrial Networking
This article is a continuation of Loop Signature 30 published in the last issue in this series, exploring reasons for non-linearities which may be encountered in feedback control loops
Read more...Loop Signature 30: Nonlinearity in control loops (Part 1) Michael Brown Control Engineering
Editor's Choice Fieldbus & Industrial Networking
If nonlinearity occurs it means that if one is to carry on controlling with the same response to changes in load or setpoint, then the tuning of the controller will also need to be adjusted to meet the new conditions.

Editor's Choice Fieldbus & Industrial Networking
In my last article I wrote about how cascade control systems can effectively overcome valve problems. This article gives another example of how a temperature control was able to perform well, in spite of really severe valve problems.

Fieldbus & Industrial Networking
A large petrochemical refinery asked me to perform an audit on several critical base layer control loops. This article deals with a problem found on a valve controlling the flow of fuel to a heat exchanger.

Editor's Choice Fieldbus & Industrial Networking
I was giving a course at a remote mine in the middle of the Namibian desert. We were discussing tuning responses, and as I always do on my courses, I mentioned that in my opinion ¼ amplitude damped tuning is not desirable, and is in fact not good.
