研究同时具有状态和控制输入的两量化器的不确定关联网络系统分散H∞状态反馈控制器和量化器参数的设计问题.由于状态在传送到控制器之前,以及控制器输入到系统时信号需要被量化,使系统的性能不能得到保证.为此,提出了一种依赖于状态调节量化器参数的策略,使得所得的闭环系统渐近稳定,并且能获得在没有量化器情况下相同的H∞扰动抑制水平.控制器的设计和量化器的参数都是根据子系统信息以分散的方式构造的.
The H∞ decentralized state feedback controllers and the quantizers' parameters of uncertain interconnected networked systems with two quantized signals in states and control inputs are studied.Since the states and control inputs need to be quantized by gerenal quantizers before passing to the controllers and systems,the systems' performance is not guaranteed.Therefore,a statet-dependent strategy for updating the quantizers' parameters is proposed,so that the closed-loop system is asymptotically stable and achieves the same H∞ disturbance attenuation level as on no quantizers circumstance.Both the designed controllers and the quantizers' parameters are constructed in a decentralized manner,depending on local information.
