Research Of Control Arithmetic Of Transformer Drying Temperature Control System Based On CAN Bus

This thesis applies CAN fieldbus to transformer Drying temperature control system and researches control arithmetic particularly. It utilizes field bus CAN of currently porpular, accomplish to organize and erect net, and emphases research intelligent control arithmetic applying extensive in currently process control domain, and carry through intelligent node and supervise control node hardware and software design.This paper researches and discusses some respect problems of fieldbus and self-organization competition networks and fuzzy-neural control networks on author comprehend abroad literature information about fieldbus and fuzzy control and neural network and genetic arithmetic and apply to transformer Drying temperature control system,and gained satisfactory effect by emulate. On this paper,adopting Back Propagation and Genetic arithmetic realize system modeling and system identification, system model drawing up better; Adopting Self-organization Competition arithmetic optimize controller,capability improve,rapid operation rate;Adopting FNNC-PID compound control arithmetic design controller and make system response rapidly and precision optimize. The results of computer emulation indicate that this method can obtain approving dynamic and static performance and good robust character. It's exceller than traditional PID controller and routine fuzzy controller.A transformer drying is a typic system which has large inertia and non-linear character. It has researchful meaning and value on this system using fuzzy-netural control arithmetic and FNNC-PID compound control arithmetic.This paper put up material software design and hardware design and control method design of transformer Drying computer control network. It's satisfactions that result of emulation.
