摘要
伴随着我国塑料制造产业产量的增大和自动化水平的上升,亟需精确性更高的控制系统性能评价方式对其生产系统运行数据进行评价,以提高产品生产效率和质量。以塑料工业生产典型的单输入/输出系统过程控制为研究对象,分别对其数据检验和预处理方式进行介绍。基于实际运行数据和时间延迟信息,提出无信号干扰状态下最小方差基数的控制系统性能评价方法。并以实际生产中可能存在的不同类型干扰信号为例,分析干扰信号模型,提出对其进行平稳化处理的方法。
As the increasing in the production of plastic industry and the improving in the automauon in China, the evaluation method with greater precision for a control system performance is required to evaluate operation data production of operation system, in order to improve the production efficiency and product quality. Based on typical process control of a single input/output system for plastic industrial production as the research object, this paper introduced the mode of data validation and data pretreatment. Based on the actual operation data and time delay information, we proposed a evaluation method for the minimum variance benchmark of control system performance without signal interference. With different types of jamming signal in the actual production as examples, the interference signal model was analyzed and its smooth processing method was put forward.
