An FPGA based heterogeneous redundant control system using controller virtualization

Abstract

This paper describes heterogeneous redundancy of FPGA based control system using cloud. Since conventional cloud servers have problems in responsiveness, we propose the concept and architecture of controller virtualization using FPGAs. However, we should consider the negative effect on the controllability by the communication delay when control is performed using the cloud. We evaluated the stability of control using cloud by means of a simulation for a representative process control model.
