The contents and the layout of this work are structured to ensure satisfactory proficiency for the novice designer. The authors provide the reader with a simple yet powerful method for designing control systems using several sensors or actuators. It offers a comprehensive control system troubleshooting and performance testing guide. This work should be a useful reference tool for: electrical, mechanical and aerospace engineers who are developing or improving products, with a need to use feedback control systems; faculty and graduate students in the fields of engineering and experimental science (for example, physics) who are building their own high-performance measuring/test arrangements; and faculties teaching laboratory courses in engineering and measurement techniques, and the students taking those courses.
