Process Control and Tuning of Industrial Control Loops
This course is designed to give you a solid understanding of the essentials of Process Control and skill you and/or your staff, in the latest procedures for the tuning of Industrial Control Loops using a minimum of mathematics and formulas.
A clear review of the principles and essentials of Process Control is given thus allowing you to gain the skills to tune a wide variety of controllers. Tuning controllers is an exact science that requires precise configuring of the process controller using the correct procedures. When the controller is set up correctly this is called tuning.
The aim of this course is to provide and/or enhance the skills required to tune a controller for optimum operation. An optimally tuned processed loop is critical for a wide variety of industries ranging from food processing, chemical manufacturing, oil refineries, pulp and paper mills, mines and steel mills.
Although tuning rules are designed to give reasonably tight control, this may not always be the objective. Some thought needs to be given when retuning a loop as to whether the additional effort is justified as there may be other issues which are the cause of the poor control. These issues will be discussed in some detail in the workshop. At the end of this workshop you will have the skills to troubleshoot and tune a wide variety of process loops.
Upon successful completion of this course, the delegates will be able to:
This course is intended for all instrumentation & control engineers, process control engineers, mechanical engineers & technicians, system integrators, consultants, operators monitoring & controlling processes, installation & maintenance technicians as well as energy management consultants, electrical engineers, electricians and automation engineers.
