一类网络化离散系统的H∞输出跟踪控制

考虑了具有量化和数据丢失的一类网络化离散系统的H∞输出跟踪控制问题。系统和参考模型的状态在传输前需要量化处理，量化误差处理为扇形有界不确定性，数据丢失建模为Bernoulli过程。基于线性矩阵不等式，得出了系统存在H∞跟踪控制器的充分条件，保证了系统的输出在H∞意义下，跟踪指定的参考模型输出。最后，数值例子表明该方法的有效性。

Network-Based H∞ Output Tracking Control for a Type of Discrete Time Systems

This paper investigated the problem of H∞ output tracking for a type of discrete network-based control sys-tems subjected to quantization and data dropout. The state of controlled system and the reference model state were quantized before being communicated. The quantization error was treated as sector-bounded uncertainty. The effect of the random packet loss was modelled as a Bernoulli process. Later, a sufficient condition was proposed for the exis-tence of H∞ tracking controllers in terms of linear matrix inequalities （LMIs）. The proposed controller could guarantee the output of the closed-loop networked control system tracks that of a given reference model well in the H∞ sense. Finally, a numerical example was prensented to show the effectiveness and usfulness of the proposed H∞ output tracking design.
