The objective of the thesis is to study the precision performance positioning of the vertical pneumatic cylinder with vertical load, and improve the stability and the reliability of the precision performance positioning. The fuzzy sliding mode controller with load compensator is implemented in the microcomputer to control the position of the vertical pneumatic cylinder with vertical load in the study. Regarding the simulation of loading force, it can be accomplished by controlling the pressure of the pneumatic proportional valve. From the experimental results, the system can still reach the positioning accuracy of 100 nm without loading effect and 150nm under different loading conditions. Comparing with the result from PID controller, the feasibility of the fuzzy sliding mode controller with loading compensator can be demonstrated by the experiment. After modifying the compensator of the system dead-zone, the stability and the reliability of the precision positioning with vertical load can be improved. |
