Abstract

A study on the stability of equilibrium points of a nonlinear system, representing the mathematical model of a pneumatic servomechanism, is developed. The characteristic equation of the linearized system appears to have a zero eigenvalue, therefore placing the problem in a critical case of stability. The solution requires the approach of Lyapunov-Malkin paradigm.
