Abstract:	Air motors have often been utilized in industrial servo systems in the automation industry due to their advantages such as small volume, low cost, light weight, convenience of operation, and no overheating problems. Recently, the development of control technology has improved, making the requirements for control precision higher than ever before. Accurate control performance in pneumatic systems is facilitated by the implementation of nonlinear control techniques. The purpose of this study is to analyze the behavior of a biaxial pneumatic table motion system with a vane-type air motor, and to design a backstepping sliding mode controller for this system. A proportional integral derivative controller compared with this new backstepping design. The tracking circle error and tracking error of the two axes are noted. The experimental results show that accurate tracking circle trajectory performance can be achieved with the proposed controller. [DOI: 10.1115/1.4004601]
