AI Technical Summary

Technical Problem

Existing technologies lack compressor control strategies that can adapt to frequent start-stop and high compression ratio conditions, resulting in low compressor efficiency, energy waste, and shortened service life, as well as pressure overshoot during gas filling.

Method used

By installing a first pressure sensor between the compressor's exhaust port and the hydrogen storage tank, the exhaust pressure is acquired in real time. The stroke coefficient is determined using a fuzzy PID control method, and the compressor's operating mode is adjusted to avoid frequent starts and stops. The compressor is also unloaded when it approaches the target pressure. Combined with initialization self-test and electric cylinder torque detection, wear is prevented.

Benefits of technology

It improves the efficiency and service life of the compressor, reduces energy consumption, suppresses pressure overshoot during gas filling, and improves the metering accuracy and system safety of gas filling.

Abstract

This invention discloses a gas filling system and its compressor control method, device, and storage medium. The gas filling system includes a compressor, a hydrogen storage tank, and a first pressure sensor. The compressor includes an exhaust port. The exhaust port and the hydrogen storage tank are connected by a pipeline. The first pressure sensor is installed on the pipeline between the exhaust port and the hydrogen storage tank. The compressor control method includes: during compressor operation, acquiring the exhaust pressure PT1 obtained by the first pressure sensor in real time; when P1≤PT1<P0, determining a stroke coefficient a using fuzzy PID based on the exhaust pressure PT1 and the compressor's current operating parameters; where P1 is a preset exhaust pressure, P0 is the target pressure of the gas filling system, and 0<a<1; controlling the compressor operation according to the stroke coefficient a. This invention enables the compressor to adapt to frequent start-stop and load-bearing start-stop conditions, which is beneficial for improving efficiency, saving energy, and extending the compressor's service life.
