چکیده
Unique characteristics of servo pneumatic systems as compliance lead to growing application of them in numerous industrial fields. However, due to higher-order nature ofpneumatic systems along with their severe nonlinearities and uncertainties, researchers have been motivated to address servopneumatic systems separately. In this aspect, an inner pressure control loop has been considered in many studies as a solution to encounter servo pneumatic systems. In this paper, a nonlinearmodel-based approach is developed for controlling pressure of an actuator chamber. Through sliding mode control approach, thecontroller utilizes a ۳/۲ on/off solenoid valve to implement pressure control task. The performance of the proposed servosystem is evaluated through several experiments and, also, compared with a proportional pressure regulator. Experimental results illustrate the competitive performance of the on/off solenoid valve with the pressure regulator. The proposed servo system possesses more robust characteristics than that ofproportional pressure regulator-included system. Furthermore, applying proposed approach, the cost, volume, and weight ofcontrolling device are reduced.کلیدواژه ها
