Some Considerations Regarding the Analysis of Pneumatic Actuators by Mathematical Models

Abstract: The paper presents a comparative analysis of mathematical models of linear pneumatic actuators. The non-linear mathematical model of the linear pneumatic actuator is deduced in the first part of the paper and presented for comparison with the linearised mathematical model. The approximation rate of the linearised model, comparative to the non-linear model, is specified on the ground of the comparative analysis of the indicial response obtained by numeric simulation. In the end the validity areas of the presented mathematical models are identified.
