A decentralized adaptive quantized feedback tracking problem is addressed for uncertain interconnected nonlinear systems in a strict-feedback form. All local state variables for each subsystem are quantized by a hysteresis quantizer. Different from the existing results in the literature, the primary contribution of this study is to establish an adaptive control design and stability analysis strategy using the local quantized state variables in the decentralized tracking field. A novel recursive design approach is presented to deal with unmatched interconnections and nonlinearities in the quantized feedback control framework, without any restrictions on virtual control laws. The total closed-loop stability is analyzed by deriving some technical lemmas on the boundedness of quantization error signals.

针对严格互连形式的不确定互连非线性系统，解决了分散自适应量化反馈跟踪问题。每个子系统的所有局部状态变量都通过磁滞量化器进行量化。与文献中已有的结果不同，本研究的主要贡献是利用分散跟踪域中的局部量化状态变量来建立自适应控制设计和稳定性分析策略。提出了一种新颖的递归设计方法来处理量化反馈控制框架中的不匹配互连和非线性问题，而对虚拟控制律没有任何限制。通过得出量化误差信号有界性的一些技术引理来分析总闭环稳定性。
