Abstract

The invention discloses a storage and supply system for a colloid micro-propulsion, a flow closed-loop feedback control method and a system, and belongs to the technical field of aerospace micro-propulsion. Including storage and supply system, flow sensor and control system. The present invention realizes propellant supply by using devices such as diaphragm tanks, piezoelectric microvalves and volume compensation, and integrates a thermal temperature difference flow sensor into the pipeline of the micro-propeller storage and supply system to realize real-time detection of propellant flow, further The feedback control signal can be output by the PID controller to control the magnitude and frequency of the voltage applied to the microvalve to realize the feedback regulation of the flow. The invention has the advantages of real-time monitoring of the supply flow rate of the propeller and maintaining a stable flow rate of the feeding system.

Description

technical field [0001] The invention belongs to the technical field of aerospace micro-propulsion, and more specifically relates to a colloid micro-propulsion storage and supply system, a flow closed-loop feedback control method and a system. Background technique [0002] With the development of modern aerospace technology, satellites tend to be miniaturized and lightweight, with the advantages of low power consumption and short development cycle. These micro-satellites have unique application advantages in communication, military, geological survey, meteorological service, scientific experiments, etc. Multiple micro-nano-satellites can be used for formation flight to complete some tasks that large-scale satellites cannot complete, such as gravitational wave detection, precise positioning, three-dimensional observation of targets, navigation, etc. Micro-nano satellites rely on micro-thrusters to achieve orbit change, orbit correction and attitude control. Compared with oth...
