摘　　要：在分析比较传统PID、Smith预估PID和模糊免疫PID原理的基础上,提出了利用模糊免疫PID调节淀粉生产线中的淀粉浓度。通过对淀粉生产线中浓度控制回路进行数学建模,对传统PID、Smith预估PID和模糊免疫PID 3种控制器进行了设计与仿真。仿真结果表明,模糊免疫PID在控制效果上明显优于传统PID并且其鲁棒性高于Smith预估PID。最后,利用Matlab的DDE协议和ActiveX与淀粉生产线的上位机RSView32进行数据交换,将Matlab中模糊免疫PID控制算法传输到上位机上,实现了模糊免疫PID控制在淀粉浓度控制中的应用。An idea that using fuzzy immune PID to regulate the density of the starch production-line was put forward after the analysis and comparison of the principle of tradition PID, Smith prediction PID and fuzzy immune PID. A mathematical model of one of density loop of starch production-line was built to design and simulate these three controllers. The simulation results show that the fuzzy immune PID is better than tradition PID on the hand of control effect and its robustness is higher than Smith prediction PID. DDE protocol and ActiveX of Matlab were adopted to realize data exchange with RSView32 of the starch production-line and transmit the algorithm of fuzzy immune PID to RSView32.
