| 摘 要： | 在常规预测控制性能指标函数的基础上加入一个表征操作变量空间变化情况的裕量损失函数,提出一种考虑裕量损失函数的预测控制新架构,并推导其优化求解过程。同时,通过稳态最优值分析新架构保留操作变量空间的效果,并采用稳态分析在预测控制中加入裕量损失函数对控制效果的影响。最后,通过实例仿真证实了新算法的有效性。

| Abstract: | Basing on the performance index function of conventional predictive control,a margin loss function which representing the space variation of operating variables was added;and a new framework of model predic-tive control algorithm which considers margin loss function(MLMPC)was proposed and its optimization solu-tion was derived.At the same time,having the steady optimal value used to analyze the effects of saving the space of operating variables and that of adding margin loss function to the predictive control.Finally,an exam-ple simulation is given to illustrate the effectiveness of this new algorithm. |
