近年来蒸煮终点卡伯值软测量的模型多采用高级智能算法来建立,其在工业控制器编程实现上存在较大难度。本文提出了一种新的软测量设计方案:利用MATLAB软件对高级智能算法的可实现性,将软测量模型建立在MATLAB中,采用OPC通信技术,使MATLAB与上位机监控软件WinCC实时交换数据,从而实现卡伯值的在线软测量。通过实验仿真表明,该系统设计方案简单易行,仿真结果真实可靠。

In recent years, many advanced intelligent algorithms are used to establish Kappa number soft measurement model of cooking endpoint, and those algorithms are difficult to programming on the industry controller. This paper proposed a new soft measurement design： Advanced algorithms could be realized by MATLAB software, so soft measurement model could be established in MATLAB, and the real-time data exchange between MATLAB and PC WinCC became possible by using OPC communications technology, then the on-line soft measurement of Kappa number was realized. Simulation experiments showed that the system design was simple and convenient, the simulation results were true and reliable.
