Development and Examination of Encrypted Control Systems

This study develops a practical encrypted control system using a DC motor and observes the properties of the encrypted control system in terms of its applicability, encrypted-induced performance degradation, and real time computation. The experimental examination demonstrates the effectiveness and the attributes of two encrypted control systems: a PID control and an observer-based control for position tracking control of the table. The authors claim that the controller encryption technique is practical and the resulting encrypted control system is a promising technology for enhancing the security of control systems.
