The invention belongs to the field of
artificial intelligence, particularly relates to a multivariable self-optimization control
coal mill agent operation method, and aims to solve the problems of variable
coupling interference, parameter solidification
lag and poor working condition adaptability in traditional control. According to the strategy, an attention mechanism-based LSTM dynamic model is constructed, and future states of six types of variables such as
air volume and temperature are predicted; defining a weighted optimization function fusing
powder making efficiency,
energy consumption, wear and stability, and introducing a soft constraint to guarantee a safety boundary; an
optimal control combination is searched on line every five seconds by adopting a depth deterministic strategy gradient
algorithm, and the four-dimensional action space of an
air door, a
hot blast valve, a
coal feeder and a
grinding roller is covered; and triggering an
incremental learning fine tuning model through residual feedback to prevent disastrous forgetting. According to the scheme, multivariable cooperation, online self-optimization and intelligent
safety control under all working conditions are realized, and the dynamic response capability and the comprehensive operation efficiency of the
coal mill are remarkably improved.
