On reliability of process control system based on fault-tolerant control
The paper expounds basic principle of fault-tolerant control,and offers how to improve the control system's reliability by means of fault-tolerant control,from both sides of hard ware and software of the control system. Finally it digs up the key technologies in fault-tolerant design. The result shows that it can be used to ensure the safety and reliability of the process control system.
