STABILIZATION THROUGH COORDINATES TRANSFORMATION FOR SWITCHED SYSTEMS ASSOCIATED TO ELECTROHYDRAULIC SERVOMECHANISMS

摘要

Electrohydraulic servomechanisms considered in this paper are modeled by five-dimensional switched nonlinear systems of control differential equations. In the stability analysis of equilibria the critical case of a zero eigenvalue of the Jacobian matrix calculated in equilibria is encountered. Local coordinates transformation and the Lyapunov-Malkin approach provide conditions for synthesis of feedback control laws that stabilize all equilibria in the closed-loop system.
