摘    要：提出了一种自适应广义预测控制策略.其中,对象参数辨识及预测模型参数计算等以较大的采样周期进行,滚动优化控制以较小的采样周期进行.将辨识与控制运算分别放在2个不同的中断服务程序中,使辨识与控制分离,通过不同采样周期的模型变换建立起辨识与控制的联系,可大大缩短控制运算时间,提高控制的实时性.

Abstract: In this paper, a new adaptive generalized predictive control strategy is proposed; plant parameter estimation and predictive model parameter recursion computation and so on are executed in a long sampling period, and roll optimization control calculation is carried out in a short sampling period. In addition, identification and control calculation are put in different interrupted routine separately. It can shorten control calculation time, and therefore, a shorter control period can be adopted.
