纸张抗张试验机调速系统设计研究

Design and Study of Speed Regulating System for a Paper Tensile Test Machine

纸张抗张试验机是用来检测纸张抗张强度的一种设备。为了使纸张抗张试验机调速系统具有更加精确的控制效果,分析了调速系统的硬件电路结构,详细介绍了MEGA16单片机和直流电机驱动芯片LMD18200的性能和特点,并提出将具有较强鲁棒性的模糊控制算法与PID控制算法相结合的控制策略。设计一个模糊PID控制器用于对直流电机调速系统的控制,并通过实验证明其具有较好的动态性能和控制效果。

Paper tensile test machine is a kind of tool used for testing the tensile strength of paper. It analyzed the hardware circuit structure of speed regulating system and introduced the performance of MEGA16 and motor driver chip LMD18200 to realize precision control. It also designed a fuzzy-PID controller by combining fuzzy control arithmetic with strong robustness and PID control arithmetic. The application of this fuzzy-PID controller in speed regulati mental results show that this fuzzy-PID controller has ng system for DC motor is completed. The experigood dynamic performance and control effect.
