系统与控制：2025–2026 年度综述

An annual survey of the eess.SY arXiv category, covering research published from September 2025 – August 2026. Built on a close-reading set of 108 papers and organised into 40 chapters, it maps the year by the field's research sub-directions.

Book framework (share of the year's output):

• Nonlinear Robust Control and Optimization (48.1%) — This subfield focuses on designing robust, optimal, and predictive control strategies for nonlinear systems under uncertainty, including multi-agent consensus and safety-critical trajectory optimization.
• Energy Systems and Smart Grid Operations (32.7%) — This area addresses real-time optimization, resource allocation, and decision-making in distributed energy systems, electric vehicle infrastructure, and smart grid applications.
• Autonomous Systems and Multi-Agent Coordination (15.3%) — This direction tackles challenges in autonomous vehicle control, multi-agent task allocation, and complex environment interaction for robotics and transportation systems.
• Cyber-Physical Security and Fault Detection (1.6%) — This subfield focuses on securing cyber-physical systems against attacks, detecting faults, and leveraging digital twins for structural health monitoring and safety assessment.
• Mathematical Foundations of Control Theory (1.2%) — This area explores fundamental theoretical aspects such as stability analysis, operator theory, differential equations, and neural operators for control systems.
• Power Electronics and Converter Control (0.5%) — This direction deals with modeling, simulation, and control of switching converters, inverters, and power electronic devices in electrical networks.
• Hybrid and Switched Systems Dynamics (0.2%) — This subfield investigates the integration of continuous and discrete dynamics, focusing on hybrid systems, delay effects, and unified modeling frameworks.
• Network Scheduling and Resource Allocation (0.2%) — This area addresses scheduling, bandwidth allocation, and service optimization in communication networks, including 5G/6G and satellite systems.
• Hierarchical Control and Coupled Systems (0.2%) — This direction focuses on hierarchical architectures, coupled systems, and matrix-based decision-making strategies for complex engineering problems.

Each sub-direction is covered across three chapters — how it framed its questions, the strength of its key findings, and its open debates and frontiers — so the reader gets a traceable picture of what this part of the field actually produced over the year.
