Recently, with rapid advancements in communication technologies, networked control systems (NCSs) have attracted significant attention. In an NCS, data to be transmitted are quantized to match the communication channel capacity. When only the quantized state is available as the feedback signal in an NCS and the actual state is unavailable, the control performance may be degraded because of the intrinsic quantization error of the quantized state. Therefore, a state estimator has to be designed to avoid the performance degradation. In this brief, we propose a synthesis for set-based state estimation in a discrete-time quantized feedback control system in which only the quantized measurement is available. The effectiveness of the proposed estimation approach is verified via both simulations and experiments.

带有量化度量的量化状态反馈控制系统中基于集合的状态估计

近年来,随着通信技术的飞速发展,网络控制系统(NCS)引起了人们的极大关注。在NCS中,要传输的数据被量化以匹配通信信道容量。当仅量化状态可用作NCS中的反馈信号而实际状态不可用时,由于量化状态的固有量化误差,控制性能可能会降低。因此,必须设计一个状态估计器以避免性能下降。在本文中,我们提出了一种在离散时间量化反馈控制系统中基于集合的状态估计的综合方法,在该系统中,仅量化测量可用。通过仿真和实验验证了所提出的估计方法的有效性。
