Due to high demand and existing courses being fully booked, Michael Brown will be running an additional course in November. This will be the combined parts 1 and 2 and will run from 25-29 November at the Johannesburg training centre.
Control Loop Optimisation Course parts 1 and 2: Part 1 is for instrument technicians control and process engineers and other people responsible for the operation and maintenance of the plant control systems. This acclaimed course offers a new insight into the practicalities of PID control. Even people with years of experience in the field will find it an eye-opener. Part 2 provides understanding of how to deal with more complex problems of control.
The training is designed to bridge the gap between theory and practice. 25-29 November at a cost of R14 296-00 (excl. VAT) if paid at least 3 weeks prior to the course. Booking should be made early as the courses are often oversubscribed.
Case history 194: Boiler level control problem. Michael Brown Control Engineering
Editor's Choice Fieldbus & Industrial Networking
A boiler level control in a petrochemical refinery was causing problems, as the level was cycling badly and taking a long time to recover from sudden load changes. In addition, there were frequent high-level alarms.

Editor's Choice
This article gives an example of an important flow control system for flare gas in a petrochemical refinery. The control was suffering from serious problems, often cycling severely, and at other times the flow process variable (PV) would suddenly move quite a lot away from the setpoint (SP).

Editor's Choice
This is the first of several articles dealing with the subject of tuning. I have found that many people think that optimisation consists solely of tuning. I would stress once again that tuning is the last thing one should do when optimising regulatory controls.

Editor's Choice
When tuning noisy loops, we recommend in our courses that one should eliminate the noise by editing it out, so the tuning will be done only on the true process response, free of any noise. The controller is controlling the process, and is not controlling the noise.

Valves, Actuators & Pump Control
Which is the weakest link in a control loop? The answer, without any doubt is that, in most cases, the final control element is the weakest link.

Editor's Choice Fieldbus & Industrial Networking
The widely held belief in many plants that tuning will solve all base layer control problems is completely fallacious. Bad tuning is generally not the main reason for loops to perform badly. It is important when performing optimisation that all elements in a loop are considered, in addition to the control strategy, before even thinking of tuning.

Editor's Choice
It is generally better to live with noise rather than filtering it out, provided it does not cause the final control element to jump around excessively.
