Puntos de equilibrio y estabilidad en lazo abierto para un servomecanismo neumático de posicionamiento

The dynamic behavior of a pneumatic servo positioning system is highly non-linear mainly due to air compressibility and the friction present in the actuator. In this paper, is presented the study of nonlinear dynamics of this system in open loop, through the determination of the equilibrium points and stability analysis. For the stability analysis of the system uses the Lyapunov's linearization method. The theoretical results of servosystem equilibrium are obtained by applying numerical methods and are compared with experimental data.
