ELECTRO-HYDRAULIC (PNEUMATIC) STAGE PROPORTIONAL CONTROL
Proceedings of the JFPS International Symposium on Fluid Power, 2002 The electrical-mechanical interfaces of servo valves and proportional valves display electromagnetic nonlinearities, such as hysteresis and saturation. In many cases, these nonlinearities have usually unfavorable effects on the performance of the whole control system.
