Title: 动态加密控制方法的比较与性能分析

Abstract: Encrypted controllers using homomorphic encryption have proven to guarantee the privacy of measurement and control signals, as well as system and controller parameters, while regulating the system as intended. However, encrypting dynamic controllers has remained a challenge due to growing noise and overflow issues in the encoding. In this paper, we review recent approaches to dynamic encrypted control, such as bootstrapping, periodic resets of the controller state, integer reformulations, and FIR controllers, and equip them with a stability and performance analysis to evaluate their suitability. We complement the analysis with a numerical performance comparison on a benchmark system. Show Chinese abstract

Abstract: 使用同态加密的加密控制器已被证明能够保证测量和控制信号以及系统和控制器参数的隐私性，同时按照预期调节系统。 然而，由于编码中的噪声增长和溢出问题，加密动态控制器仍然是一项挑战。 在本文中，我们回顾了动态加密控制的最新方法，如自举、控制器状态的周期性重置、整数重构和FIR控制器，并为其配备稳定性与性能分析以评估其适用性。 我们通过在基准系统上的数值性能比较来补充分析。
