Fault diagnosis based on monitoring and sensory signals plays an important role in avoiding catastrophic accidents and enormous economic losses. This study presents a fault diagnosis scheme for hydraulic servo system using compressed random subspace based ReliefF (CRSR) method. From the point of view of feature selection, the scheme utilizes CRSR method to determine the most stable feature combination that contains the most adequate information simultaneously. Based on the feature selection structure of ReliefF, CRSR employs feature integration rules in the compressed domain. Meanwhile, CRSR substitutes information entropy and fuzzy membership for traditional distance measurement index. The proposed CRSR method is able to enhance the robustness of the feature information against interference while selecting the feature combination with balanced information expressing ability. To demonstrate the effectiveness of the proposed CRSR method, a hydraulic servo system joint simulation model is constructed by HyPneu and Simulink, and three fault modes are injected to generate the validation data.<\/jats:p>","DOI":"10.1155\/2018\/8740989","type":"journal-article","created":{"date-parts":[[2018,2,18]],"date-time":"2018-02-18T23:31:55Z","timestamp":1518996715000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Fault Diagnosis for Hydraulic Servo System Using Compressed Random Subspace Based ReliefF"],"prefix":"10.1155","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1053-8475","authenticated-orcid":false,"given":"Yu","family":"Ding","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6571-4854","authenticated-orcid":false,"given":"Fei","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1537-5820","authenticated-orcid":false,"given":"Zhen-ya","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4593-1936","authenticated-orcid":false,"given":"Wen-jin","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,2,18]]},"reference":[{"key":"e_1_2_7_1_2","first-page":"1546","article-title":"Performance assessment of hydraulic servo system based on bi-step neural network and autoregressive model","volume":"15","author":"Lu C.","year":"2013","journal-title":"Journal of Vibroengineering"},{"key":"e_1_2_7_2_2","doi-asserted-by":"crossref","unstructured":"HeX.
