The Research Of PET Preform Multi Infrared Heating Control System Base On Online Fuzzy PID

PET perform temperature control system is one important part of the bottle blowing and filling machine. The quality of the control system design directly determines the quality of the blowing bottle. Beverage filling machine is the drink bottle production line equipment, is the component of the blowing bottle, filling and capping function. Comparted with the traditional discrete system, the filling machine is more intelligent. Bvit the same time, the complexity of control system is also increase, especially for the PET perform tenqierature’s fast and accurate control. The fast and the accurate control of the PET perform temperature determines the final shape of the beverage and the efficiency of the production. So the PET perform temperature control system design is very important.This paper is based on the scientific research subject,. According to the rapid control requirements of PET perform temperature and the complexity of the control model, put forward the fozzy-PID intelligent control strategy implementation. This article mainly includes following several parts.First, the Pet perform temperature control system platform will be introduced. It includes the nmin PET perform heating scheme, the system hardware platform and the software platform of the system.Secondly, according to the PET perform temperature control system requirements to analysis the system model, and compare with the current variety industrial control strategy.Combined with the ARM embedded control characteristic, select and design fuzzy PID as the control strategy of PET performs temperature control system.Finally, analyzed the stability of the control system and anti-interference, and make the contrast of traditional PID and fbzzy PID. Record the effect of the tow kinds of commonly used industrial control algorithm separately used in the perform temperature control system.
