摘　　要：基于IMC-PID原理,采取实际应用的PID模型,实现了理论算式与工程实际的结合。对不同时滞程度的一阶系统进行参数整定,确定了λ的取值范围。利用NCD解决了大量计算问题,为参数优化提供了有效途径。通过设计举例,显示出系统具有良好的控制性能。再经过一般性分析,得出了内模控制的一般规律,以供工程设计参考。Based on the IMC- PID principle,by using the practical PID model,the combination of theoretical calculation and practical engineering was realized. Through the different degree of first order delay system parameter setting,the value range of lambda is determined. By utilizing the NCD,a large amount of calculation can be performed,which provides an effective way for the parameter optimization. By giving a concrete example,the system showed good control performance. And after a general analysis,the general rule of the internal model control was obtained,which provides a reference to engineering design.
