ABSTRACT: Temperature is the most common physical quantity in the production process, a lot of production processes regard temperature as it and is accused of the parameter. It is at electric heat of smeltery bed among control system, time heavy , pure to lag behind coefficient of temperature time the long in constant temperature, when change the sex by characteristic not obvious, this make on the basis of accuse of target routine , mathematics of model control the method, fuzzy to control method and expert intellectual control ,etc. method have greater limitation but unable to win the ideal control result in temperature control.
In this, we use the single neuron PID of BP neural network to control algorithms , adopt the traditional one-chip computer temperature control system, temperature of bed is it control to go on to smeltery electric heat, in order to is it work systematic dependability and security to improve, achieve the with high efficiency , high-standard goal.
