摘　　要：给出了利用OMRONC200HαPLC实现Smith补偿算法的方法.在PLC上编制Smith补偿算法应用程序时,可以利用PID控制指令,还要应用定点运算指令解决浮点数的计算问题.以铝合金厂工业电阻炉的炉温控制为工业应用背景,探讨了该实现方法的实用性.The method of using OMRON C200Hα PLC to implement Smith compensating algorithm is given in this paper.When using PLC programming language to realize the Smith compensating algorithm, the PID instruction could be used, in addition the fixing-point operation instruction could also be used to solve the floating-point data operation problem.This paper discusses the practicability of this realizing method, under the application background of the industrial boiler's temperature control system of aluminium alloy factory.
