NONLINEAR MODELLING AND FEEDBACK LINEARIZATION OF VAVLE-CONTROLLED ASYMMETRICAL CYLINDER

Abstract

Abstract: The state equations is deduced for the valve controlled asymmetrical cylinder system when the cylinder moving forward and reverse, and one nonlinear model is finally integrated. The model proves correcly through simulation and experiment. On the basis of the mentioned work, adopting input-output accurate linearization in nonlinear control theory, the global linear model is achieved by nonlinear state feedback transforming, and the stability of it’s zero dynamic state is analyzed. This research is available for realizing high accuracy hydraulic servo system’s position control by adopting the linear control theory.

Key words: Global linear model, Valve controlled asymmetrical cylinder Nonlinear, Zero dynamic state
