Description
technical field [0001] The invention belongs to the technical field of air pressure control systems, and in particular relates to a fully automatic air pressure control system and method based on PID control. Background technique [0002] Air pressure control systems are widely used in industry, transportation, medical and other industries. In the medical industry, precise pressure control of gas is required, such as quantitative injection control of biochemical reagents, liquid flow, pipeline cleaning and other systems that require precise air pressure control. [0003] The existing air pressure control system can ensure that the load system maintains a constant pressure within a certain period of time by controlling the cylinder at one time. However, the air pressure in the independent air pressure control system will slowly decrease with use, and a slight air leak in the system will also lead to insufficient air pressure. Contents of the invention [0004] In order to...
