Abstract
According to fuzzy self-tuning PID adjustment method
collected temperature signal from DS18B20 is transmitted to the microprocessor LPC2103
the corresponding control valve is controlled to achieve the temperature process control of the steam heating cans
the sugar content of preserved fruit kiwi is regulated effectively.Kiwi preserves quality is improved.The control system is simple
and is able to overcome the delay characteristics of the object temperature well.It has short control response time
