An engineering method for the power flow assessment in servo-actuated automated machinery: Mechatronic modeling and experimental evaluation. (April 2016) - Oliva, Enrico
Abstract: In this paper, an engineering method for the power flow assessment of a position-controlled servo-mechanism is outlined. The considered system is composed of a permanent magnet synchronous motor coupled to a standard power converter, and directly connected to a slider crank mechanism. After the accurate description of a consistent power flow model, a sequential identification technique is discussed, which allows to determine the dynamic parameters of linkage, electric motor and electronic driver by means of non-invasive experimental measures. The proposed model allows to accurately predict the major sources of power loss within the system. Abstract : Highlights: Description of a Power Flow (PF) model within a servo-actuated mechanism. PF employing a Linear-in-Parameters (LP) formulation. Description of a sequential PF identification method. Experimental validation on an industrial case study.
