Objective To analyze the existing problems of the traditional pneumatic position control system and propose a new position control system. The method uses a new actuator - a new cylinder with built-in brake and displacement sensor. System position control using PWM method and fuzzy control algorithm to achieve, when the cylinder reaches the target position, the use of brake to achieve the position of the cylinder to maintain. Experimental results show that the rigidity of the system has been significantly improved, the positioning accuracy of 0.15mm. Compared with different cylinder positioning system with brake, the system has no big impact and wear. Conclusion Pneumatic position control system to solve the problems of the traditional pneumatic position control system, has good practical value
