摘要
新型带存取装置的快递柜解决了现存快递柜存取数量有限、空间利用率低的问题,但在快递存取速度上还有待提高。借助于模糊控制理论,先利用MATLAB设计了一个模糊控制器;模糊控制器的输入为快递质量、高度和底面积,输出为电机转速,以此确定不同快递存取过程中匀速时的速度。然后针对快递存取加速阶段设计了模糊PID(proportion integral differential,比例-积分-微分)控制器,借助于MATLAB/Simulink软件进行仿真,并与一般的PID控制进行了比较。结果表明,加速阶段采用的模糊PID控制方式的系统响应速度快且稳定性高,因此该模糊控制方法有助于提高快递的存取速度。
The new-type express cabinet with access device solves the problems of limited access and low space utilization afflicting the existing express cabinet,but the speed of express access needs to be improved. A fuzzy controller was firstly designed with MATLAB on the strength of the theory of fuzzy control,which selected the mass,height and bottom area of express delivery as input variables and the motor speed as the output variable to determine the speed of different express access processes at uniform speed. Then,a fuzzy PID (proportion integral differential) controller was designed for the acceleration stage of express access. Simulation of the fuzzy PID control was carried out with the help of MATLAB/Simulink software,compared with the general PID control. Results show that the fuzzy PID control method adopted at the acceleration stage boasts fast response speed and high stability,which is proven to improve the speed of express access.
