摘要
常用的非线性预测控制算法先构造合适的多面体描述系统包裹原非线性系统,通过研究多面体描述系统的各个顶点系统的稳定性来保证原非线性系统的稳定性。在以前研究中,多面体描述系统保持不变,但事实上多面体描述系统与终端约束集密切相关。设计了一种根据终端约束椭圆集调整多面体描述系统的非线性预测控制方法,该方法能够有效地减小系统的控制性能指标,同时控制过程中的终端不变椭圆集及其内的反馈控制律具有离线指导作用。
Nonlinear model predictive control usually constructs a polytopic description system including the nonlinear system.The stability of each vertex of the polytopic description system guarantees that of the nonlinear system. The polytopicdescription system has not been tuned before, but in fact it is related to the terminal invariance ellipsoidal set. In this paper, wetune the polytopic description system by the invariance set online. This method can effectively reduce the cost index. Moreimportantly, the invariance ellipsoidal set and feedback controller can be used in next control.
