Problems solved by technology
Therefore, in the feedback control, good control can be performed when the culture characteristics of the solid culture show gentle changes, but when the culture characteristics of the solid culture show rapid changes, the reaction lags and it is difficult to bring the product temperature closer to the temperature. The case of product temperature target value
[0006] On the other hand, in the fuzzy control as described above, smooth control is possible, but the rules are complicated and it is difficult to determine the rules
Also, it's hard to tell what impact each rule will have
Therefore, in fuzzy control, the content of the output calculation is complex, requiring a high degree of control device and control technology

Embodiment Construction
[0025] Hereinafter, one embodiment of the present invention will be described with reference to the drawings. figure 1 It is a schematic configuration diagram of a ventilated solid culture device 1 according to an embodiment of the present invention. A circular culture bed 3 is arranged in the heat-insulated culture room 2 . The bottom surface of the circular cultivation bed 3 is a perforated plate, which can be ventilated. The circular cultivation bed 3 rotates around the central cylinder 4 . The inside of the culture chamber 2 is divided into an upper chamber 5 and a lower chamber 6 via a circular culture bed 3 . The air passing through the air conditioner 10 flows into the cultivation chamber 2 , and the air flowing out from the cultivation chamber 2 is exhausted through the air conditioner 10 . The air flowing into the lower chamber 6 flows into the upper chamber 5 through the solid culture 7 on the circular culture bed 3 . Thus, the solid culture 7 on the circular cu...

The invention provides a device and a method for product temperature control of a solid culture. The device and the method can realize good product temperature control of a solid culture without a complex output operation. The device is used for product temperature control of a solid culture cultured by a ventilated solid culture device. According to solid culture cultural characters changing with time, a deviation operation value of a product temperature target value and a product temperature measured value is corrected so that a controlled output is determined. Therefore, the controlled output is a value obtained according to the proleptic solid culture cultural characters; the response lag is reduced; and a product temperature of a solid culture can be controlled well. Based on cultural character data of a solid culture, a deviation operation value is operated and corrected and thus an output operation is simple and good control is realized without a high-level device and a high-level technology.
Description
technical field [0001] The invention relates to the product temperature control of solid culture cultured by a ventilated solid culture device. Background technique [0002] Feedback control is known as an example of product temperature control of solid cultures. Figure 8 A block diagram showing an example of product temperature control of a solid culture using feedback control. The deviation calculation unit 100 included in the control device 105 calculates a deviation calculation value from the product temperature target value and the product temperature measurement value, and the output calculation unit 101 determines a control output for the deviation calculation value. This control output is input to the air conditioner 102 to perform air conditioning, thereby changing the product temperature of the solid culture 103 . The changed product temperature is measured by the product temperature measurement unit 104 , and the product temperature measurement value is input to...
