The multi paper papermaking machine system is affected by nonlinearity and time-varying factors. In order to improve the accuracy of quantitative control,a fuzzy PID based quantitative control method for multi paper papermaking machines is proposed. Extract the dynamic characteristics of the quantitative loop and identify the factors that affect the quantification of multiple paper machines;Analyze the rules of the PID controller to determine the impact of control parameters on the quantitative control results of multiple paper machines. Based on the analysis results,propose an internal model control method to determine the PID controller parameters,eliminate time-varying effects and reduce overshoot during the control process;Finally,in order to eliminate nonlinear interference,the fuzzy PID control method is used to adjust the quantitative influencing factors of multi grade paper machines,output corresponding control quantities,and achieve quantitative control of multi grade paper machines. The experimental results show that the proposed method has good quantitative control effect,low overshoot,and timely optimization of controller parameters.
