PIDTutor has released a book entitled 'Mastering Cascade Control', which is designed to help technicians and engineers to implement and troubleshoot split-range control applications.
Cascade control uses two controllers with a single control valve to provide faster, more accurate control response to upsets.
It can be used for several different applications, such as heat exchangers, tank levels and distillation column control.
It is widely used in process industries such as pulp and paper, oil and petrochemicals and mining.
'This is a practical book for plant technicians and engineers, using straightforward rules and guidelines, without the complex math,' said George Buckbee, president of PIDTutor and author of the book.
'Mastering Cascade Control' covers all aspects of cascade control use.
Starting with the basics, the book discusses when to use cascade and when to avoid it; costs and benefits of cascade; how to configure the control strategy; how to commission the system, tune the loops; and how to train operators and troubleshoot problems.
