Aiming at the nonlinearity, long time-delay and other such influencing factors for cigarette weight control, this
paper analyzes the problems existing in the traditional PID control algorithm. And puts forward designing methods for
cigarette’s weight fuzzy control system based on TMS320F2812 DSP. The working principle and overall structure of
cigarette weight control system has been analyzed, and the mathematical model of each system component part has been
studied. Based this work, a system simulation model has been established. At the same time, the design of the fuzzy controller
has been completed through analysis and induction of the practical operating experience and expert knowledge.
Through simulation researches, the results show that the cigarette weight fuzzy control system than the PID control system,
has faster dynamic response speed, shorter adjusting time and smaller system overshoot. In system design, fuzzy control
method can effectively ensure the stability and rapidity of cigarette weight control. Furthermore, the results prove that
the fuzzy controller design method is correct and effective.
