Significant progress has been made using model-based observers. However, their performance depends on an accurate system model, which is often difficult to obtain such a model. This is especially true for unknown hybrid systems with periodic jumps. To address this gap, this paper presents two classes of data-driven estimation approaches for unknown hybrid systems with periodic jumps. An estimation law is constructed directly from noisy input/measured data using the S-lemma. Systems explaining the data are derived for unknown dynamical hybrid systems by virtue of the behavioral theory of systems. A criterion on global exponential stability is established by employing data-based linear matrix inequalities. A data-driven hybrid estimation scheme is designed to eliminate the system model identification step. Under mild conditions, the global exponential stability of systems explaining the data is guaranteed theoretically. In particular, the obtained results are applied to a data-driven hybrid switched-gain estimation framework.

Conventional point observers, such as Kalman or Luenberger designs, often produce fragile estimates that degrade in the presence of disturbances and modeling errors. Interval observers (IOs), in contrast, enclose the true trajectories within clearly defined upper and lower bounds, providing guaranteed robustness, resilience to uncertainty, and formal safety assurances beyond what traditional methods can offer. This paper proposes a robust multi-step interval observer (IO) for discrete-time systems that combines a predictive structure with convex linear matrix inequality (LMI) design to deliver certified bounds with improved reliability and efficiency. The key innovation is a q-step predictive structure that aggregates system dynamics over a selectable horizon to enhance accuracy, disturbance rejection, and delay resilience. Observer gains are computed via a single convex LMI, ensuring non-negative error dynamics without coordinate transformations or iterative tuning. The effectiveness of the proposed framework is demonstrated on two challenging applications: a non-minimum phase (NMP) unmanned aerial vehicle (UAV) subject to wind disturbances and model mismatch, and a Lithium-ion battery management system (BMS) performing state-of-charge (SOC) estimation under sinusoidal load variations. In both cases, the proposed IO achieves tighter interval bounds (<span><math><mo>±</mo></math></span>0.1 % vs. <span><math><mo>±</mo></math></span>2.5 %), faster convergence and reduced computation.

The classical Round-Robin (RR) protocol stands out for its advantage in scheduling the data transmission of complex networks (CNs) with limited communication bandwidth. Nevertheless, the excessive sacrifice of the observability of the CNs leads to the inevitable degradation of estimator performance. A novel scheduling mechanism called the Grouped-Round-Robin (GRR) protocol is thus first proposed to govern the data transmission of nodes within the NTD-MNs, and simultaneously overcome the deficiency of the conventional RR protocol. Besides, considering the openness of the communication environment, cyber-attacks are usually inevitable, and stochastic deception attacks modeled with a Bernoulli process are thus taken into account. Employing the proposed GRR protocol, a state estimator is established which considers the impact of deception attacks on the measurement output. Then, sufficient conditions are derived to ensure that the estimation error for the discussed system is ultimately bounded in mean square.
