Overview ?

Introduction

Although the subject of many hundreds of articles, books, and courses, the basic elements of automatic process control are still widely misunderstood. Worse, the majority of control systems are misapplied. Research carried out by ISA and other bodies indicates that up to 75% of all loops will oscillate when operated in automatic.

This workshop, Process Instrumentation: Process Control and Loop Tuning, is designed to provide engineers and technicians with the basic theoretical and practical understanding of the process loop and how this can be applied to optimize process control in terms of quality, safety, flexibility and costs.

Personal impact

On successful completion of this workshop delegates will be able to:

understand the fundamentals of Process Control
analyze such problems as valve hysteresis, stiction and non linearities
fully appreciate the effects of proportional, integral and derivative control
correctly apply both open and closed Loop Tuning according to Ziegler Nichols
apply Lambda Tuning
realize the effects of filtering on loop performance
value the effect of valve sizing on control loop performance
recognize the effect of different control algorithms on loop tuning performance
understand cascade and feedforward control
identify and correct problems with process dead time

Organisational impact

Following the training and development experience provided by this workshop, participants will return to their organizations equipped with new skills and knowledge that will enable them to understand, analyse, and optimize automatic control when applied to a closed loop industrial control system.

By leveraging these skills your enterprise can expect an improvement in overall productivity, safety, and flexibility, coupled with a reduction in costs, through the ability to analyze problems and successfully tune PID loops.

Workshop objectives

Designed for both novice and experienced engineers and technicians, this workshop provides an insight into modern closed loop control practices through an in-depth investigation into the four basic elements of any control system:

the process;
the transducer (sensing element plus transmitter);
the final control element; and
the controller.

Throughout the workshop, participants will learn through active participation using exercises, questionnaires, and practical simulation sessions covering:

process reaction
tuning methods
diagnostic tools
affect of different algorithms
