模糊PID控制及其在H型钢连轧张力控制中的应用

以二机架连轧为基础,根据H型钢连轧装置的系统模型和张力模型,采用模糊PID的变形结构控制器,实现无张力控制或微张力控制。仿真结果表明,该控制方法比传统PID控制更好的改善了系统的动态性能,提高了稳态精度。

Based on the two-stand continuous rolling,according to H profiled bar continuous rolling system model and tension model,the transmutation structure controller of fuzzy PID is applied to realize distension control or micro-tension control.The simulation results indicate that this control method can improve the systems dynamical performance and enhance its static precision contrasting than the traditional PID control system.
