Temperature fault-tolerant control system of the CSTR with coil and jacket cooling based on VPC

For the exothermic reaction CSTR with dual cooling system of coil and jacket characteristics, temperature dual control system solution is proposed based on the redundancy of equipment operating functions. In the light of the depth analysis in the dual control works and the experimental study of semi-physical simulation, CSTR temperature dual control system is not only able to get a good quality control and energy saving, but also has a passive fault-tolerant capacity for the jacket cooling fault and initiative fault-tolerant potential for the coil cooling fault. The initiative fault-tolerant of coil cooling fault can be achieved through the design of fault diagnosis for the coil cooler and control strategy of initiative fault-tolerant. The process monitoring and fault-tolerant control of CSTR temperature control system, the security improvement of exothermic CSTR production can be achieved through temperature fault-tolerant control system of the exothermic reaction CSTR with coil and jacket cooling based on VPC which has the characteristics of CSTR temperature dual control, the process fault diagnosis and the initiative fault-tolerant control. Finally, the effectiveness of system is verified by semi-physical simulation experiments.
