How to minimize the tilting of the MEMS mirror plate during its large linear scan is a major problem in this application. In this work, an FTS system has been constructed based on a biaxial MEMS micromirror with a large-piston displacement of 180 \u03bcm, and a biaxial H\u221e robust controller is designed. Compared with open-loop control and proportional-integral-derivative (PID) closed-loop control, H\u221e robust control has good stability and robustness. The experimental results show that the stable scanning displacement reaches 110.9 \u03bcm under the H\u221e robust control, and the tilting angle of the MEMS mirror plate in that full scanning range falls within \u00b10.0014\u00b0. Without control, the FTS system cannot generate meaningful spectra. In contrast, the FTS yields a clean spectrum with a full width at half maximum (FWHM) spectral linewidth of 96 cm\u22121 under the H\u221e robust control. Moreover, the FTS system can maintain good stability and robustness under various driving conditions.<\/jats:p>","DOI":"10.3390\/s18020508","type":"journal-article","created":{"date-parts":[[2018,2,9]],"date-time":"2018-02-09T12:46:27Z","timestamp":1518180387000},"page":"508","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["H\u221e Robust Control of a Large-Piston MEMS Micromirror for Compact Fourier Transform Spectrometer Systems"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0157-4896","authenticated-orcid":false,"given":"Huipeng","family":"Chen","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, HangZhou DianZi University, Hangzhou 310018, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mengyuan","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, University of Florida, Gainesville, FL 32611, USA"},{"name":"School of Information and Electronics, Beijing Institute of Technology, Beijing 100081, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Mechanical and Electronic Engineering, Shangdong University of Science and Technology, Qingdao 266590, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8393-0021","authenticated-orcid":false,"given":"Huikai","family":"Xie","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, University of Florida, Gainesville, FL 32611, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chang","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, HangZhou DianZi University, Hangzhou 310018, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhangming","family":"Peng","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, HangZhou DianZi University, Hangzhou 310018, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shaohui","family":"Su","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, HangZhou DianZi University, Hangzhou 310018, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,2,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Griffiths, P.R., and De Haseth, J.A.
