A Method for Improving the Positioning Accuracy of Linear Pneumatic Actuators

Mihai Avram

Abstract


The paper proposes a novel method for improving the positioning accuracy of a linear pneumatic system, by means of piezoelectric compensation of the error. The mathematical model of the system is proposed and discussed. Also, the model is simulated and a test is used to determine certain parameters of the system. A test stand is built and the experimental results are presented.

Keywords
