Abstract

In this paper, a fuzzy control with friction compensation is developed to deal with a nonlinear pneumatic positioning system characterized with friction, unknown system model, and external disturbance. In order to enhance the positioning accuracy, a control scheme is designed for compensating the friction effect of the moving stage. Positioning experiments based on the derived control strategy were performed to show and validate the proposed control performance. As two experimental examples of positioning results in a total of 30 experimental trials for the stepwise input positioning controls, the positioning accuracy with less than 30nm was verified for both forward and backward actuations with step commands. Hence, the control scheme provided in this paper that could significantly improve the positioning performance of a traditional pneumatic positioning system is demonstrated.
