网络化预测控制器设计的多目标最优化框架

Multi-objective optimization framework for networked predictive controller design

Sourav Das, Saptarshi Das, Indranil Pan

摘要:

网络化控制系统(NCSs)经常遭受随机数据包丢失的问题,从而影响系统的稳定性和性能。针对通信网络封闭的反馈控制系统中随机丢包的不利影响,设计了一种具有预测增益的状态反馈控制器。为了实现更好的性能,本文提出了一种基于线性矩阵不等式(LMI)约束的优化控制器设计框架,以确保稳定性。采用非支配排序遗传算法-Ⅱ(NSGA-II)对不同的冲突目标函数进行了优化。在本文中提出的方法不仅给出了保证闭环稳定的意义上的李雅普诺夫,即使在存在随机丢包,但也给出了两个冲突的时域控制目标之间的优化权衡。

英文摘要:

Networked Control Systems (NCSs) often suffer from random packet dropouts which deteriorate overall system's stability and performance. To handle the ill effects of random packet losses in feedback control systems, closed over communication network, a state feedback controller with predictive gains has been designed. To achieve improved performance, an optimization based controller design framework has been proposed in this paper with Linear Matrix Inequality (LMI) constraints, to ensure guaranteed stability. Different conflicting objective functions have been optimized with Non-dominated Sorting Genetic Algorithm-II (NSGA-II). The methodology proposed in this paper not only gives guaranteed closed loop stability in the sense of Lyapunov, even in the presence of random packet losses, but also gives an optimization trade-off between two conflicting time domain control objectives.
