Abstract
Increase continuously along with the our country food yield, the baking dry of the food, store to become a count for much problem.Currently, our country north of in the food baking dry, main usage steam and hot breeze dryer.In recent years, the hot breeze dryer category is many, the development velocity is quick, being very produce the unit is welcome.But, usually the hot breeze dryer of type of tower controls the calculate way for the PID, for the control parameter that the different food needs to be regulate different, and for temperature isetrol, usually for opposite and slow-moving change, if the adoption PID calculate way, the overshoot quantity workload of the very difficult control and the whole computing of system parameter and conditionings is very huge.The fuzzy control is a kind of language controller, the ability is more for the best controller of similar reaction- The person's control behavior, it has the different from the control stability, ability more convenient realization pais object of very strong robustness to control, this some small scaled production units are very meaningful. The main research of this text is the fuzzy control calculate way of the type of tower hot breeze food dryer system of the misty inference engine according to a machine of 89 C51s of the company of ATML, the temperature semaphore collects the system, the baking dry system and the design and realizations of the man-machine interface, make it contented actual demand within production line.
