Mathematical modeling and analysis of the electrohydraulic actuator with the throttle control

Abstract

Annotation High demands to modern electrohydraulic actuators are placed. This applies to the static and dynamic characteristics of the drives, which is achieved by using different correcting devices (controllers). In the article analysis of the most effective regulator for an electro-hydraulic actuator is conducted during the comparison of its dynamic characteristics at introduction of various types of correcting devices: the introduction of state controller, the introduction of additional pressure feedback and a proportional controller. Block diagrams of the electrohydraulic actuator are constructed according to the corresponding mathematical models. The optimization of the control parameters was carried out to improve the static characteristics of the actuator.
