Research on Electric Heating Cut Tobacco Dryer Based on Fuzzy PID Control Algorithm

PID control has many advantages such as good robustness, high reliability, simple algorithm, flexible use, etc., and is widely used in the field of industrial control. In the process of cut tobacco drying, there are problems such as time delay, non-linearity, time-varying of the drying object, and it is difficult to establish an accurate mathematical model. As a result, the conventional PID controller has problems such as poor tuning, poor performance, and poor adaptability to the controlled process. In view of the above problems, this paper presents a self-tuning fuzzy PID control algorithm with the advantages of no need to set up accurate mathematical model and good robustness. The simulation results show that the response is faster, the temperature control of the dryer can achieve good results, meeting the requirements of high-quality production.
