A novel testing approach for SSRF digital power supply controllers

Digital power supply controller is one of the key parts of SSRF high resolution high stability magnet power supply system. It is very essential to keep any degradation of these excellent properties by any stages as small as possible via careful testing when the controller is developed. In this study,a novel testing approach was presented,with which a novel closed control loop without actual power converter was constructed,and the new developed SSRF Digital Controller can work well in it.

从失序到再序:生成式人工智能下的信息秩序变局与治理

以ChatGPT为代表的生成式人工智能促动信息秩序的巨大变局,重新分配社会信息资源和数字权力。数据喂养的偏狭、使用的偏误和伦理的偏颇为生成式人工智能输出的虚假信息、错误信息及恶意信息流入信道创造条件,现有信息秩序面临失序风险。调整信息治理范式与治理方向成为智能传播格局下AI治理的题中应有之义。本文提出实现信息秩序再次和谐的共创进路与治理方向,即以法律为约束,构建软硬法兼施的复合型AI信息治理法律框架,将法治贯彻到生成式人工智能信息治理的全链条多领域,全面提升法律规制效能;以内外兼顾的技术善治实现技术真正服务于社会价值和公共利益的图景,促动技术的自我纠偏与完善;构建生成式人工智能流域化治理模式以直面多元治理难题,将多元数字行动主体纳入差异化规制与协同性治理体系以实现信息秩序的复建。
