AI Technical Summary

Technical Problem

In existing mine monitoring and linkage systems, there is a fluid dynamics and physical coupling conflict between dust control water curtains and local ventilation fans. Traditional single-variable fixed threshold feedback control has response lag. The pure time delay of mine airflow has strong time-varying characteristics. The gravity dissipation of water mist exhibits gradual lag. Decoupling compensation of fixed parameters is prone to causing instability of the control system when there are abrupt changes in the flow field topology or fluctuations in pipeline pressure.

Method used

The system employs a state perception module to collect multi-dimensional physical field state variables in real time. A safety interlock module drives the control state machine to switch when the dust concentration meets the warning range. A perturbation identification module generates pseudo-random sequence instructions for discrete vector displacement integration. A gain update module performs normalization calculations. A residual decoupling module removes interference. A collaborative execution module generates dynamic feedforward compensation instructions to achieve adaptive control of the system.

Benefits of technology

It overcomes waveform phase disorder caused by time-varying lag in mine airflow, suppresses environmental background noise, adaptively adjusts dynamic feedforward compensation commands, reduces the probability of actuator signal jumps when switching control modes, and ensures the accuracy and stability of fan regulation.
