Out of control: Why control systems go wrong and how to prevent failure

Date of publication:
Series code:

The analysis of incidents in this publication remains unchanged from the first (1995) edition and while there have since been substantial advances in control system technology, both the overall findings and the more detailed lessons remain applicable and valid. For this version there has been a comprehensive revision of references.

Also featuring minor guidance changes reflecting revisions of legislation and relevant standards. The booklet's primary purpose is to raise awareness of the technical causes of control system failure by examining actual case studies of incidents that show that obvious defects could have been prevented. For users of control systems, designers, manufacturers and installers. Supported throughout by colour illustrations and easy-glance diagrams and information tables.
