摘要
工业过程中的非最小相位被控对象因其具有反向特性而会给控制器设计带来困难,在自动化教学中对非最小相位概念的描述通常偏重于零点位置、零动态等理论概念,因缺乏直观性而使得学生不易理解透彻。结合自适应控制课程教学,基于工业过程中典型的空气加热混合过程,通过合理构造实验条件,构建了具有非最小相位特性的物理被控对象装置,在此基础上,研发了自校正控制教学实验平台,可以开展非最小相位工业对象的辨识、控制和自校正控制的教学实验,有助于加深自动化专业学生对非最小相位概念的理解,从而改善教学效果。
Industrial processes with non-minimum phase dynamics always cause special difficulties for controller design because of its reverse characteristics.In automation courses,introduction to non-minimum phase usually focuses on the theoretical concepts such as zero position,or zero dynamics,and it is difficult for students to comprehend deeply due to the lack of intuition.For the course of adaptive control,we have established a physical non-minimum phase industrial device based on typical air heating and mixing process in industrial environment by choosing reasonable experimental conditions.Furthermore,an experimental platform for teaching and learning of self-tuning control is developed,which can be used in caring out the experiments of identification,control and self-tuning control for non-minimum phase industrial objects.It can help automation students in their studies related to non-minimum phase concept,and improve teaching effectiveness.
