摘　　要：烟丝含水率是影响卷烟品质和口感的重要参数之一,过高或过低的烟丝含水率都会导致卷烟燃烧不良、口味差异较大等问题;为了有效地提高卷烟产品的质量稳定性,基于MFA-SM设计一种细支卷烟烟丝含水率自动控制系统;该系统框架有三层,即MFA-SM前端采集层、中间层以及终端控制层;设计系统硬件,包括水率数据采集设备、MFA-SM控制器、驱动器、微雾加湿器与干燥设备;利用水分仪采集烟丝含水率,并利用无线射频模块将数据传输给MFA-SM控制器,控制器运行双环控制模块中的内环为滑模控制模块,用于计算干燥设备控制参数,外环为无模型自适应控制模块,用于计算微雾加湿器控制参数;根据控制参数控制干燥设备和微雾加湿器运行,实现烟丝含水率自动控制;实验结果表明,设计系统应用下,含水率误差低于0.3%,拟合优度为0.952,具有更好的控制效果。The moisture content of tobacco is one of the important parameters affecting the quality and taste of cigarettes,and high or low moisture content can lead to issues such as poor combustion and significant variations in taste.In order to effectively control the stability of tobacco moisture content and improve the quality consistency of cigarette products,an automatic control system for the moisture content of fine tobacco in cigarettes based on model free adaptive-sliding mode(MFA-SM)is designed.The system framework consists of three layers:the MFA-SM front-end acquisition layer,intermediate layer,and terminal control layer.The hardware of the system includes the moisture data collection equipment,MFA-SM controller,driver,mist humidifier,and drying equipment.the moisture analyzer is used to collect the moisture content of tobacco,and transmit the data to the MFA-SM controller via a wireless RF module.The controller runs a dual-loop control module,with the inner loop being a sliding mode control module,calculates the control parameters for the drying equipment,and the outer loop is a model-free adaptive control module for calculating the control parameters for the mist humidifier.The drying equipment and mist humidifier are controlled based on these parameters to achieve the automatic control of tobacco moisture content.Experimental results show that under the application of the designed system,the moisture content error is less than 0.3%,and the goodness of fit is 0.952,indicating its better control effectiveness.
