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.
