Variational Encrypted Model Predictive Control
Jihoon Suh, Yeongjun Jang, Junsoo Kim +1
We develop a variational encrypted model predictive control (VEMPC) protocol whose online execution relies only on encrypted polynomial operations. The proposed approach reformulat…
ARX-Implementation of encrypted nonlinear dynamic controllers using observer form
Deuksun Hong, Donghyeon Song, Mingyu Jeong +1
While computation-enabled cryptosystems applied to control systems have improved security and privacy, a major issue is that the number of recursive operations on encrypted data is…
Asymptotic stabilization under homomorphic encryption: A re-encryption free method
Shuai Feng, Qian Ma, Junsoo Kim +1
In this paper, we propose methods to encrypted a pre-given dynamic controller with homomorphic encryption, without re-encrypting the control inputs. We first present a preliminary…
Asymptotic tracking control of dynamic reference over homomorphically encrypted data with finite modulus
Shuai Feng, Junsoo Kim
This paper considers a tracking control problem, in which the dynamic controller is encrypted with an additively homomorphic encryption scheme and the output of a process tracks a…
