Fault Simulation and Identification of an Electrohydraulic System by Using Fault Emulation

Abstract

Hydraulic systems work under harsh conditions and fault diagnosis is of vital importance. The right set of sensors to collect data for the possible faults should be selected. In this paper, an electrohydraulic system model is established on Simscape on the Matlab platform, and typical hydraulic faults are simulated by using the software. Later, the data-driven approach was employed by using the Matlab Diagnostic Feature Designer Toolbox and Feature Classification Toolbox for best fit for fault identification.
