摘要
传统的Smith预估器是解决大纯滞后系统控制的有效方法,但它依赖于被控对象精确的数学模型,使应用受到了限制。带积分的模糊Smith预估器兼有前者的特性,又不依赖于对象精确的数学模型,且有较强的鲁棒性。论文给出了设计方法及在电加热炉中的应用结果。
Though the Smith predictor controller is useful for a time-delay control system,it depends on the accurate mathematic model of a controlled object.So its industrial application is limited.The integrated fuzzy Smith predictor is also valid for a time-delay system.It can reduce the limitation of the above-said model and guarantee the robustness to the disturbance.The design method is described in the paper.The result of application shows that it is useful for the temperature control of electric ovens.
