Abstract

The invention discloses a BP-PID-based tobacco sheet coating rate control method and device. The method comprises the steps: establishing a BPNN model suitable for the tobacco sheet coating rate; taking the output of the BPNN model as the input of a PID model, and establishing a BP-PID control model; obtaining training parameters of the BPNN model, and carrying out optimization training on the BP-PID control model; and controlling the coating rate of the tobacco sheets in real time by using the trained BP-PID control model. A PID control strategy (BP-PID) with a BP neural network is adopted, PID control parameters are adjusted in real time through the BP neural network, so that the system has self-adaptability and self-learning capacity, the coating rate of the tobacco sheet production process can be controlled on line after reasonable self-adaptive learning, and therefore the optimal control effect is achieved.

Description

technical field [0001] The invention relates to the technical field of tobacco sheet coating rate control, in particular to a BP-PID-based tobacco sheet coating rate control method and device. Background technique [0002] BPNN: BP neural network (BPNN, Back Propagation Neural Network), that is, a multi-layer network for weight training of nonlinear differentiable functions. [0003] PID: PID controller (PID is the abbreviation of Proportional (proportional), Integral (integral), and Differential (differential)), that is, a control algorithm that combines the three links of proportional, integral and differential, and its essence is based on the deviation of the input The value is calculated according to the functional relationship of proportional, integral and differential, and the result of the calculation is used to control the output. [0004] Tobacco flakes are produced from waste tobacco impurities in cigarette production. High-quality tobacco flakes taste similar to...
