摘要
针对传统制糖离子交换工艺系统的不足,利用爱默生PLC设计了离子交换流量模糊控制系统。提出把模糊控制理论和PID控制理论相结合的方法,设计实现模糊-PID复合控制系统。通过Matlab仿真可看到将模糊控制算法与PID控制原理相结合相互补偿的方法与常规PID控制方法相比,模糊控制PID系统具有控制精度高,可靠性好,适应性好的优点。
Aiming at various shortcomings existing in the traditional refine sugar technology,the fuzzy PID controller in ion exchange is designed utilizing Emerson series PLC.A fuzzy--PID hybrid control system is designed base on combining the fuzzy control theory and method of PID control theory. Through Matlab simulation it is found that the fuzzy PID controller is higher precision ; more reliable and good adaptation than the traditional PID controller.
