Identification of Friction Parameters in Pneumatic Cylinders using a Combined Real-Time and Simulation Environment

D. Saravanakumar, B. Mohan

Abstract


This paper presents a method to identify the friction parameters for servo-pneumatic systems using a combined-reality environment. To acquire system friction parameters accurately can be extremely difficult once the servo-system has been assembled because of its highly nonlinear nature, which causes a great difficulty in servo-pneumatic system modelling and control. In this paper, a combined-reality environment has been used to determine the friction parameters easily and efficiently through online identification technique. The advantages of this method are simplicity, speed and high accuracy in the estimated parameters. Using this method the frictional parameters of two different sized cylinders are identified.
