摘要
目的分析传统气动位置控制系统存在的问题，提出一种新的位置控制系统．方法采用新的执行机构——内藏制动装置和位移传感器的新型气缸．系统的位置控制采用ＰＷＭ方法和模糊控制算法实现，当气缸达到目标位置后，利用制动装置来实现气缸的位置保持．结果实验研究表明，系统的刚性得到明显提高，定位精度达到０．１５ｍｍ．与不同带制动装置气缸定位系统相比，本系统无大的定位冲击和磨损．结论气动位置控制系统解决了传统气动位置控制系统存在的问题。
Aim To present a new kind of pneumatic position control system based on the analysis of the disadvantages of conventional pneumatic position control systems. Methods The new kind of pneumatic position control system used a new kind of actuator cylinder with a built in brake and a displacement sensor. And PWM control method and fuzzy control algorithm were utilized in the system to control the position of the cylinder, and the brake was used to fix the cylinder to its target position after it reached the position.Results The stiffness of the system was experimentally proved to be greatly improved and the position precision to be within 0 15 mm. In addition, the system is free of great shock and wear. Conclusions The new kind of pneumatic position control system is free of the disadvantages of conventional systems, and is of practical value.
