Abstract

The invention discloses a temperature control method based on a fuzzy self-adaptive controller. The temperature control method is realized via the fuzzy self-adaptive controller, a three-phase voltage-regulating module, a heating module and a temperature sensor. The fuzzy self-adaptive controller is composed of generalized prediction control and fuzzy control. The fuzzy self-adaptive controller is generated via combination of the generalized prediction control and the fuzzy control. The generalized prediction control or the fuzzy control are selected by the fuzzy self-adaptive controller to realize flexible control of a heating system according to different error situations of the system so that heating is more uniform, temperature control is more accurate and thus industrial production efficiency is enhanced.

Description

Technical field:

[0001] The patent of the present invention relates to a temperature control method, in particular to the design of a fuzzy adaptive controller. Background technique:

[0002] In industrial production, some processing techniques have strict requirements on heating temperature. Too high or too low temperature may cause immeasurable losses, so how to strictly control the temperature has become an important issue. Commonly controlled electric heaters have a wide heating range. When industrial production requires high temperature control, common controlled electric heaters often cannot meet the more precise control requirements, and in some industrial production, common controlled electric heaters are used. Electric heaters are easy to cause uneven heating, resulting in poor heating effect.

[0003] In some productions that require manual feeding, it is difficult to ensure the uniformity of the weight and volume of each feeding, resulting in uncertain system mod...
