基于DR-PID与HarmonyOS的滤棒成型纸制动控制器

  目的  解决成型纸制动装置结构复杂、零配件易磨损、维修繁琐等问题。  方法  对成型纸制动系统的工作原理进行研究，使用运行HarmonyOS的华为Hi3861国产芯片，采用抗扰PID（Proportional-Integral-Derivative control）算法建立数据模型，并在Matlab软件中的Simulink模块下对该算法进行仿真实验，设计出一种制动控制系统。  结果  装有该系统的滤棒成型机与之前相比在启动时、搭接时、运行时和停车时，断裂次数分别下降了96%、91.2%、96%、88%和92.6%，总断裂次数降低了92.6%，且满足结构新颖简单、维修方便、控制精准的要求。 

Brake controller of wrap paper system based on DR-PID and HarmonyOS

  Objective  This study aims to solve defects of the forming paper brake device, including complex structure, quick-wearing spare parts and tedious maintenance.  Methods  The working principle of the forming paper brake system was studied. Data models were constructed by using Huawei Hi3861 domestic chip running HARMONYOS and antichard PID (ProPormressional-DeriVative Control) algorithm. The algorithm was simulated under the Simulink module in the MATLAB software, and a brake control system was designed.  Results  The breaking times of the filter rod forming machine equipped with this system decreased by 96%, 91.2%, 96%, 88% and 92.6% respectively, and the total breaking times decreased by 92.6%, which meets the requirements of novel and simple structure, convenient maintenance and accurate control.
