The invention discloses a high-frequency electromagnetic valve fine adjustment control method which comprises the following steps: S1, setting the initial range B of fine adjustment control and the initial frequency C of action of a high-frequency electromagnetic valve; S2, adjusting pressure; S3, obtaining the action times of the high-frequency electromagnetic valve during the pressure adjusting process, and judging whether the action times of the high-frequency electromagnetic valve is equal to or greater than a first preset value during the pressure adjusting process, if yes, return to S1; otherwise, carrying out S4; and S4, controlling the high-frequency electromagnetic valve by taking the current initial range B and the current initial frequency C as optimal control points. With adoption of the high-frequency electromagnetic valve fine adjustment control method, the action times of the valve port of the electromagnetic valve can be greatly reduced, and the purpose of stably adjusting actual pressure to target pressure after pressure adjustment is realized.
Description
technical field [0001] The invention relates to the technical field of high-frequency electromagnetic valves, in particular to a fine-tuning control method for high-frequency electromagnetic valves. Background technique [0002] In the prior art, the fine-tuning control technology of the high-frequency solenoid valve uses a wide fine-tuning range and a large number of solenoid valve port movements to achieve stable adjustment of the target pressure. When fine-tuning, the high-frequency action of the high-frequency solenoid valve is used to control the inflow and outflow of a very small amount of gas each time to achieve the final stability to the target pressure. [0003] With the above settings, although the fine-tuning and stabilization of the target pressure can be completed well in the end, and the controllability is easy to grasp, it requires many times of control of a small amount of gas, which is realized at the expense of increasing the number of actions of the high-...
