Problems solved by technology

Since the internal gas trajectory curve is required to be stable and has rapid step changes, the terminal pressure obtained by this method is not smooth, has a large hysteresis, and is highly dependent on technical operators
Therefore, it cannot simulate the working conditions of gas well.

Description

technical field [0001] The invention relates to a helium pressure regulating system, in particular to a high-pressure helium control system for fast and accurate automatic pressure regulation of terminal output pressure of a high-pressure helium energy system. Background technique [0002] Gas hydraulic servo is a servo system that uses gas pressure as the primary energy source to drive the turbo pump to rotate at high speed to generate hydraulic power output to the servo actuator. [0003] The automatic pressure-regulating high-pressure helium control system is a control system that simulates the internal ballistic characteristics of the gas hydraulic servo and replaces the gas with high-pressure helium. The internal ballistic characteristics are used to describe the change characteristics of the output terminal pressure of the helium blowing system with time. Ideal The internal ballistic characteristic curve is as figure 1 shown. Therefore, how to quickly and accurately ...
