THE VELOCITY CONTROL OF THE ELECTRO-HYDRAULIC SERVO SYSTEM
International Journal of Research in Engineering and Technology, 2014 In general two basic methods are used for controlling the velocity of a hydraulic cylinder. First by an axial variable-displacement pump for controls flow to the cylinder. This configuration is commonly known as a hydrostatic transmission. Second by proportional valve powered by a constant-pressure source, such as a pressure compensated pump, drives ...
