摘　　要：针对管材在线定长切割过程中位置和速度跟踪控制的难点问题,研发了以基于ARM9 S3C2416微处理器的控制器为核心的定长切割控制系统,并且采用基于自适应模糊PID控制器的伺服闭环控制系统,实现了管材定长切割的高精度控制。主要讨论了定长切割控制系统的硬件和软件设计、伺服系统建模、自适应模糊PID伺服跟踪技术的应用。实践证明:该控制系统采用触摸屏代替PLC,功能稳定,实时性高,操作灵活方便;采用自适应模糊PID控制器可明显提高其动态响应性能及定长切割的精度,使控制系统具有成本低、可靠性高、抗干扰能力强、控制精度高等优点,能够满足定长切割的精度要求。To solve the problems in the positioning and velocity tracking control of pipes＇on-line selected-length cutting process, a con- trol system based on ARM9 $3C2416 microprocessor with touch screen is developed, using the closed-loop servo based on adaptive fuzzy PID control algorithm, which realizes high-precision control of the pipes＇selected-length cutting. The hardware, software design of the selected-length cutting control system, the servo system modeling and the application of adaptive fuzzy PID servo tracking technology in the system are discussed. Experiment has proved that the control system using touch screen can take the place of PLC, which operates stably and conveniently with high real-time performance. Using the adaptive fuzzy PID controller can significantly improve the dynamic response performance and the accuracy of the selected-length cutting, the control system has advantages of low costing, high reliability, having strong anti-interference ability, high control accuracy and robustness to meet the precision requirements of selected-length cutting.
