摘要
燃烧系统是一个具有大惯性、纯滞后、分布参数非线性的系统，PID调节以及双交叉限幅PID控制在燃烧系统中控制效果不理想、超调量和响应时间的矛盾不能解决、系统抗干扰的能力比较差。在培烧炉的控制中，采用双交叉限幅控制和模糊控制相结合的方法，选用西门子公司的S7—400PLC实现了上述控制功能，得到了比较好的控制效果。
The combustion system is of large inertia, pure time delay, and non-linear parameter distribution. The PID regulation and the dual crossing amplitude restrietion＇s PID can not obtain ideal control effects in the combustion system and solve the contradiction between exceeding adjustment amount and response time. The said systems also were not able to resist the interference. In the calciner control, the dual crossing restriction＇s PID control with the fuzzy logic control is adopted through Siemens S7-400 PLC and the above said functions are realized thus achieving more satisfactory control effects,
