This study employs front-end signal processing at the sensing node to alleviate computations at the control node and results in a simplistic sum of weighted inputs to determine a control force. The control law simplifies to U = WP, where U is the control force, W is a pre-determined weight matrix, and P is a deconstructed representation of the response of the structure to the applied excitation. Determining the optimal weight matrix for this calculation is non-trivial and this study uses the particle swarm optimization (PSO) algorithm with a modified homing feature to converge on a possible solution. To further streamline the control algorithm, various pruning techniques are combined with the PSO algorithm in order to optimize the number of entries in the weight matrix. These optimization techniques are applied in simulation to a five-story structure and the success of the resulting control parameters are quantified based on their ability to minimize the information exchange while maintaining control effectiveness. It is found that a magnitude-based pruning method, when paired with the PSO algorithm, is able to offer the most effective control for a structure subject to seismic base excitation.<\/jats:p>","DOI":"10.3390\/a14100292","type":"journal-article","created":{"date-parts":[[2021,10,9]],"date-time":"2021-10-09T23:37:08Z","timestamp":1633822628000},"page":"292","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Utilizing the Particle Swarm Optimization Algorithm for Determining Control Parameters for Civil Structures Subject to Seismic Excitation"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3522-0516","authenticated-orcid":false,"given":"Courtney A.","family":"Peckens","sequence":"first","affiliation":[{"name":"Department of Engineering, Hope College, 27 Graves Place, Holland, MI 49423, USA"}]},{"given":"Andrea","family":"Alsgaard","sequence":"additional","affiliation":[{"name":"Department of Engineering, Hope College, 27 Graves Place, Holland, MI 49423, USA"}]},{"given":"Camille","family":"Fogg","sequence":"additional","affiliation":[{"name":"Department of Engineering, Hope College, 27 Graves Place, Holland, MI 49423, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9211-482X","authenticated-orcid":false,"given":"Mary C.","family":"Ngoma","sequence":"additional","affiliation":[{"name":"Department of Engineering, Hope College, 27 Graves Place, Holland, MI 49423, USA"}]},{"given":"Clara","family":"Voskuil","sequence":"additional","affiliation":[{"name":"Department of Engineering, Hope College, 27 Graves Place, Holland, MI 49423, USA"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1567","DOI":"10.1061\/JSDEAG.0003280","article-title":"Concept of structural control","volume":"98","author":"Yao","year":"1972","journal-title":"J.
