免疫遗传PID在工业自动化通用平台上的实现

Realization of immune genetic PID based on industry automation platform

针对目前免疫遗传PID在工程应用中存在的问题,采用图形化组态技术,在工业自动化通用技术平台IAP上实现基于在线免疫遗传算法的PID控制器组态,通过仿真实验分析了免疫遗传PID在阶跃响应和扰动情况下的性能指标.仿真实验结果表明,IAP平台上的免疫遗传PID具有与MATLAB相同的控制性能和控制效果,说明在IAP平台上实现先进控制算法的可行性和有效性.利用IAP兼容包括PLC在内的多种控制站等优点,可以把控制逻辑组态下载到实际的工业控制中,实现免疫遗传PID应用的通用性.

According to the problems in engineering application of recent immune genetic PID control- ler, online PID controller configuration based on immune genetic algorithm is realized on Industry Au- tomation Platform （IAP） by adopting the graphical configuration technology, the performance indica- tors of immune genetic PID are analyzed in the case of step response and disturbance in simulation ex- periment. Immune genetic PID controllers are proved to have the same control performance and result on both platforms through comparing the simulation outputs on MATLAB and IAP, which shows the feasibility and effectiveness of realizing advanced control algorithm on IAP. Taking advantage of IAP which is compatible with a variety of controllers including PLCs, configuration of logic can be down- loaded to industrial control directly, realizing the general application of immune genetic PID.
