Dynamics and design of a power unit with a hydraulic piston actuator

Abstract

The problem of the preselection of parameters of a power unit of a mechatronic complex on the basis of the condition for providing a required control energy has been discussed. The design of the unit is based on analysis of its dynamics under the effect of a special-type test conditional control signal. The specific features of the approach used are a reasonably simplified normalized dynamic model of the unit and the formation of basic similarity criteria. Methods of designing a power unit with a hydraulic piston actuator that operates in point-to-point and oscillatory modes have been considered.
