It consists of a hydraulic source, an actuator, a control element, connecting pipelines, etc. These systems are widely used in various industrial and mechanical applications, including fields such as automobiles, aerospace, construction, agriculture, and manufacturing.

[0031] The working principle of the hydraulic control system is based on Pascal's law, that is, the pressure exerted by the liquid in a closed container will be evenly transmitted to all parts of the container.
