Summary: | This paper presents a sliding mode control scheme to
control a class of electro-hydraulic actuator system. A reaching
law and varying boundary layers approaches are proposed in the
scheme. The reaching law is aimed to solve the effect of
chattering and minimize the reaching time. While, varying
boundary layers algorithm is applied to ensure position tracking
accuracy and smooth control action. The system is presented with
the inclusion of friction and internal leakage in the system model.
The proposed controller abilities are investigated through
simulations works in Matlab Simulink environment based on the
existing system parameters. The results indicate that the
proposed scheme successfully reduces the reaching time,
eliminates the chattering effect, improves the tracking accuracy,
and results a smooth control action. In general, this improvement
offers a significant contribution for accuracy in modern
equipments positioning applications. |
