Design and Simulation for Control System of Tobacco Leaf Roasting Based on Fuzzy-PID Control
This paper aimed at the characteristics of the control system of baking in different period of tobacco leaf roasting process, intelligent control system of tobacco leaf roast control tactics based on fuzzy-PID is proposed. A designing method and Implementation algorithm of fuzzy-PID is given. For the difficulty of traditional PID controller parameters adjusting, the PID parameters were adjusted online by using fuzzy reasoning method. It can combine the advantages of general fuzzy control and traditional PID control in this method, and it is simulated and compared with general PID control on the simulation platform of MATLAB control box. The simulation results show that the fuzzy self-tuning PID controller has good dynamic response curve, short response time, small overmodulation, high steady state precision, and good dynamic and static performance by comparing with the traditional PID controller. Therefore temperature and humidity control of tobacco leaf roasting will perfectly improved by fuzz PID control.
