A study on tracking position control of an electropneumatic system using backstepping design

Abstract

As an important driving element, the pneumatic cylinder is widely used in industrial applications because of its reliable, cheap and excellent performance in an industrial servo system. However, along with the development of control technology, the requirement for control precision gets higher and higher. In many cases, in order to achieve the satisfied control performance, the effects of nonlinear factors contained is considered in the plant. Backstepping is one of these nonlinear control techniques which has attracted a great deal of research interest in recent years. It is mainly applicable to strict-feedback system. This paper presents a new form of backstepping controller for an electropneumatic system. Notice that the model of this system is not under strict-feedback form. Then, a modified methodology is proposed, synthesized and implemented on an experimental test bench. Experimental results are presented and discussed.

Backstepping sliding mode tracking control of a vane-type air motor table motion system

“…The device is able to compensate for uncertainties including the force of friction. A tracking position control system based on the backstepping design has been proposed for an electropneumatic device, consisting of a cylinder and two valves [10]. Synchronous control for mutual positioning of two vertical-type pneumatic servo systems is proposed in [11].…”

“…A number of investigations have been conducted on fuzzy control algorithms [4], adaptive control [5], backstepping control [6], and robust linear control [7].…”

Control of a pneumatic drive using electronic pressure valves

“…Thus it is possible to perform flexible, fast and precise positioning tasks of pneumatic actuators. As a result, much research has been carried out, dealing with the development of various control concepts for pneumatic drives for motion or force control (Liu and Bobrow, 1988;Hurmuzlu 2000a, 2000b, and bibliographies therein; Smaoui et al, 2006;Surgenor and Vaughan, 1997;Xiang and Wikander, 2004). In many studies, relatively expensive proportional servo-valves have been used, which, however, give the best results, especially in applications where precise positioning and smooth motion are required.…”
