项目摘要

Super-resolution control based on quantized input/output and softly specifiedcontrol problems are considered to establish a fundamental control framework based on low-resolution signals. As for quantized input control, dynamic quantizers are extended to multi-rate systems, and a design method of optimal dynamic quantizers is proposed with its optimal performance. Also, it isextended to a class of nonlinear dynamical systems. An analytical solution is obtained for input affine systems. Furthermore, a new type of quantizers which utilize dither signals are discussed, and its performance is analyzed. As for quantized output control, a noise tolerant system identification method is proposed based on signal projection. A few methods have been developed to reconstruct the system state based on the system models and the quantized output. As for softly specified control, a mathematical framework is given to describe the stabilization problem in term of bounded finite invariant sets. For systems with periodic input, a method to produce relevant inputs to keep the system trajectory in an invariant set. Furthermore, a method is proposed to achieve soft tracking via practical stabilization techniques, and its effectiveness is validated through some experiments using mobile robots.

考虑基于量化输入/输出和软指定控制问题的超分辨率控制，建立基于低分辨率信号的基本控制框架。对于量化输入控制，将动态量化器扩展到多速率系统，并提出了一种具有最优性能的最优动态量化器的设计方法。此外，它还被扩展到一类非线性动力系统。获得输入仿射系统的解析解。此外，还讨论了一种利用抖动信号的新型量化器，并分析了其性能。针对量化输出控制，提出了一种基于信号投影的耐噪声系统辨识方法。已经开发了一些方法来基于系统模型和量化输出来重建系统状态。对于软指定控制，给出了一个数学框架来用有界有限不变集来描述稳定性问题。对于具有周期性输入的系统，一种产生相关输入以将系统轨迹保持在不变集中的方法。此外，提出了一种通过实际稳定技术实现软跟踪的方法，并通过使用移动机器人的一些实验验证了其有效性。
