AFP: Chinese scientists develop intelligent control system to enhance the performance of space reactors! The movement of space nuclear reactors, such as pitch, roll, and yaw, affects neutron dynamics and thermofluid dynamics models. This article was published by AFP on June 3, 2025. Researchers from Central South University of China, Tsinghua University, and Technical University of Munich have developed an advanced uncertainty model and intelligent control system that improves the responsiveness and adaptability of space nuclear reactors in complex environments. The new system features faster response time, higher control accuracy, and stronger adaptability to changes. This uncertainty is exacerbated by the dynamic motion of space reactors, such as pitch, roll, and yaw, which affect neutron dynamics and thermofluid dynamics models. Additionally, environmental interference affecting sensors and actuators also introduces uncertainty. Quantifying this uncertainty is crucial for ensuring safe and reliable operation. Traditional PID controllers struggle to cope with uncertain systems and often fail to achieve optimal control. The complexity of space reactors and the strength of parameter coupling make it difficult to manually determine the optimal control parameters. To overcome this challenge, the team adopted the NSGA-II intelligent method for controller optimization, achieving more stable and precise control. This study also analyzes the uncertainty coupling mechanism inside the reactor and implements an intelligent control system that enhances system responsiveness and load tracking accuracy under uncertain conditions. These advancements are expected to provide more adaptive and interference-resistant control systems for advanced nuclear energy systems, bringing potential benefits to future intelligent reactor control research and the entire nuclear industry.
