摘要
针对先进控制技术在下位控制系统中的应用问题,采用水箱模拟工业控制中常见的一阶被控对象。通过S7-300控制器,采用SCL语言编写矩阵运算功能块,实现了动态矩阵控制算法。水箱液位定值试验表明,在正常及扰动状态下,动态矩阵控制算法都取得了良好的控制效果。对于动态品质要求较高的控制系统,动态矩阵控制的实现效果明显优于传统PID控制。
Be aimed at the issue of applying advanced control technology in subordinate control systems, the water tank is adopted to emulate the commonly seen 1st order controlled object in industrial control. Through S7-300 controller, the matrix operation functional block is programmed by using SCL language to implement dynamic matrix control algorithm. The test of water tank level indicates that in normal and disturbed condition, excellent control effects are obtained. For control systems requesting high dynamic quality, the effect of dynamic matrix control is obviously better than traditional PID control.
