Abstract: This article considers an integrated process control approach that integrates SPC with EPC.The approach is used to monitor the complex system simulation for the manufacturing process comprising the second-order dynamic process and the steady-state disturbance ARMA(1,1).Its key is the design of EPC controller.The common model of EPC is provided,after analysis of the MMSE and PID controllers’ state-space models by state space method.At last,the effectiveness of the scheme is verified through comparison the performance of MMSE,PI controllers and the proposed controller in this paper.
Key words: Statistical Process Control(SPC), Engneering Process Control(EPC), dynamic processes
摘要: 针对较为复杂的二阶动态过程和稳态干扰ARMA(1,1)组成的系统模拟制造过程,采用SPC与EPC整合的集成过程控制方法,实现对全过程的监控。整合的关键是EPC控制器的设计。将状态空间分析法引入到对EPC控制器的设计中,并通过分析MMSE和PID控制器的状态空间模型,得出EPC控制器的一般设计模型。最后通过仿真实验,比较MMSE、PI控制器和文中设计的控制器的监控性能,验证了该方法的有效性。
