Process Control of Gas-solid Fluidized Bed Based on Arma Model

Based on ARMA model,a novel method of process control of gas-solid fluidized bed was proposed.ARMA models of the signals acquired by 24PC series pressure sensors of Honeywell company ware constructed,and their autoregressive ordern was identified subsequently.Flow patterns were identified by threshold of order n.Experimental results show that this method is effective in industrial process control.
