广义预测PID控制算法

GPC Algorithm for PID Control

本文根据广义预测控制(Generalized Predictive Control,简写GPC)与PID控制控制律结构的相似性,通过对广义预测控制性能指标函数中控制加权序列Qj(z-1)的配置给定,导出了具有PID算法结构的广义预测控制律。从而借助广义预测控制算法参数的递推关系链,自动优化整定PID调节参数,并实施广义预测PID控制。

As GPC law is similar with PID control law, by configuring control sequence Qj （z^-1） of GPC performance function, GPC law of PID algorithm structure is educed. Accordingly PID controller parameters are tuned optimally and automatically in virtue of GPC algorithm parameters relation chain, and GPC-PID strategy is implemented.
