Experiments of Pneumatic Linear Positioning with Conventional Control System

Abstract

In a great number of industrial applications the pneumatic positioning systems are used often, because of good ratio between load and supplied power, in spite of fact that these systems present nonlinear behaviour. In this paper, a pneumatically actuated linear positioning system is controlled using a classical PID. Simulations were performed using a software program available from the suppliers of the pneumatic unit to evaluate responses, and then the tests were repeated on the laboratory bench available. Software simulation results were compared with those obtained on real hardware.
