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.
Abstract：This paper investigated the problem of H∞output tracking for a type of discrete network-based control systems 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 existence 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.
