Dynamic controller that operates over homomorphically encrypted data for infinite time horizon
Junsoo Kim, Hyungbo Shim, Kyoohyung Han
In this paper, we present a dynamic feedback controller that computes the next state and the control signal over encrypted data using homomorphic properties of cryptosystems, whose…
Distributed Algorithm for Economic Dispatch Problem with Separable Losses
Seungjoon Lee, Hyungbo Shim
Economic dispatch problem for a networked power system has been considered. The objective is to minimize the total generation cost while meeting the overall supply-demand balance a…
Comprehensive Introduction to Fully Homomorphic Encryption for Dynamic Feedback Controller via LWE-based Cryptosystem
Junsoo Kim, Hyungbo Shim, Kyoohyung Han
The cryptosystem based on the Learning-with-Errors (LWE) problem is considered as a post-quantum cryptosystem, because it is not based on the factoring problem with large primes wh…
Output feedback based event-triggered sliding mode control for delta operator systems
Kiran Kumari, Bijnan Bandyopadhyay, Kyung-Soo Kim +1
In this paper, we present an output feedback based design of event-triggered sliding mode control for delta operator systems. For discrete-time systems, multi-rate output sampling…
Robust Stability of Discrete-time Disturbance Observers: Understanding Interplay of Sampling, Model Uncertainty and Discrete-time Designs
Gyunghoon Park, Chanhwa Lee, Youngjun Joo +1
In this paper, we address the problem of robust stability for uncertain sampled-data systems controlled by a discrete-time disturbance observer (DT-DOB). Unlike most of previous wo…
