摘　　要：针对工业领域中矿仓料位控制的纯滞后 ,提出了Smith预估器的控制策略。以ABB公司的控制平台为基础 ,将现代控制理论和计算机技术相结合 ,构成了纯滞后补偿控制系统 ,有效地克服了纯滞后和外因扰动引起的料位波动。实际应用表明 ,该系统具有控制品质高、鲁棒性好和抗干扰能力强等优点。To against the dead time characteristic of ore silo material level control in industry field, the control strategy of Smith predictor is stated. With Control platform of ABB as the foundation, and combining modern control theory with computer technology, a dead time compensation control system is structured. The dead time characteristic and the level fluctuation caused by external disturbance are overcome effectively. The practical application shows that the system offers high control quality, robustness and high anti-interference capability.
