【Abstract】 This paper systematically reviews the theory and applications of prescribed-time control. On the theoretical level, it sorts out the achievements in the fields of nonlinear systems, multi-agent systems, and systems with special constraints and faults, and analyzes the control algorithms and design principles, such as the dynamic scaling parameter method and time-scale transformation method for nonlinear systems, and the key points of distributed algorithm design for multi-agent systems. On the application level, it discusses its applications in aerospace, industrial automation, power systems and other fields, and analyzes how to improve system performance and reliability, such as high-precision control of spacecraft rendezvous and docking, and timely task completion of industrial automation production lines. At the same time, it analyzes the challenges of system uncertainties and distributed control of large-scale complex systems, and looks forward to the future development directions of interdisciplinary integration and optimization of networked and distributed control, providing references for research in this field.更多还原
