Numerical Simulation Approach of a Pneumatic Actuator to Force Perturbation

The paper presents the dynamic behavior of a pneumatic actuator of a positioning control system in the presence of a force perturbation. The perturbation force is considered as a function of time which can appear at an unexpected moment. Also, it can action together with technological force. Numerical simulations have shown that the pneumatic control system followup the input and reject the perturbance. The pneumatic control system is stable and robust.
