Pneumatic and Hydraulic Components and Instruments in Automatic Control covers the proceedings of the International Federation of Automatic Control (IFAC) Symposium. The book reviews papers that tackle topics relating to the use of pneumatic and hydraulic equipment in automatic control. This text discusses topics such as dynamic behavior analysis of pneumatic components by numerical techniques and application of bond graphs to the digital simulation of a two-stage relief valve dynamic behavior. Topics including mathematical modeling of cavitation in hydraulic pumps; pro and contra electro-fluid analogies in digital simulation of fluid circuits; and improvement in accuracy of pneumatic delay are covered as well. This book will be of great use to researchers and professionals whose work involves the designing of automatic control systems.
