The first link of this robot is driven by an Alternating Current Brushless Permanent Magnet Motor (ACBPMM) through a three-phase multi-level inverter with 27 levels of voltage per phase. Thanks to the topologies offered by ACBPMMs and to the multi-level inverter, high commutation frequencies are reduced, as observed in the computer simulations. Additionally, to determine which proposed control strategies are the most suitable for an ACBPMM connected to a multi-level inverter, a comparative study on the performance of the controllers implemented for this robot is conducted.<\/jats:p>","DOI":"10.3390\/sym13010086","type":"journal-article","created":{"date-parts":[[2021,1,6]],"date-time":"2021-01-06T20:45:42Z","timestamp":1609965942000},"page":"86","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Design, Analysis, and Comparison of Control Strategies for an Industrial Robotic Arm Driven by a Multi-Level Inverter"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7197-8928","authenticated-orcid":false,"given":"Claudio","family":"Urrea","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, Universidad de Santiago de Chile, Avenida Ecuador 3519, Estaci\u00f3n Central, Santiago 9170124, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Jara","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Universidad de Santiago de Chile, Avenida Ecuador 3519, Estaci\u00f3n Central, Santiago 9170124, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1318","DOI":"10.1109\/TLA.2013.6710378","article-title":"Fault-Tolerant Controllers in Robotic Manipulators.
