Completing Volume 2, Part 1 of this series, this volume covers the control systems technology option as required by the syllabuses of C&G 2240 Part 2 and BTEC level 2/3; certain topics are expanded to provide a bridge to the Part 3 syllabus. The approach is practical and non-mathematical throughout and many of the assessment objectives can be achieved by following exercises in system training simulators. The book provides a suitable scheme for in-course assessment to a standard demanded by both C&G and EEB. It can also be used as a self-study course for students and those interested in extending their knowledge of control systems principles. The eight appendices cover answers to test questions, examination and syllabus structure, the EEB practical test, a skills assessment checklist and surface mount component codes, as well as a multilingual glossary of technical terminology, and notes on report writing.
