摘要
This paper analyzed the disadvantages of conventional pneumatic position control systems, then presented a new kind of position control system, which used a new kind of actuator-cylinder with a built-in brake unit and a displacement sensor. A PWM control scheme and fuzzy control algorithm are utilizied in the system to control the position of the cylinder, and the brake is used to fix the cylinder to its target position after it reached the position. The stiffness of the system is experimentally proved to be greatly improved and the position precision to be well than +/-0.15mm. In addition, the system is free of great shock and wear.
