In this paper, the general probabilistic fuzzy set is proposed, and the convergence analyses of its secondary probability density function (PDF) are conducted. It discloses the distribution regularity of membership degree in general PFS, which improves the information and interpretability of PFS. Then, according to convergence, a new method to tuning parameters for PFLS is proposed. This method avoids the parameters into local inefficiency, and also reduces the number of learning parameters in PFLS. Last, the new tuning method is applied to the electromyography (EMG) robots modeling problem. The comparison shows that the probabilistic fuzzy logic system based on general PFS (GPFLS) can achieve a simple modeling process, and also, it improves the learning speed compared to PFLS. The work presented will improve the potential application of probabilistic fuzzy logic system.<\/jats:p>","DOI":"10.3233\/jifs-171121","type":"journal-article","created":{"date-parts":[[2019,6,4]],"date-time":"2019-06-04T12:32:38Z","timestamp":1559651558000},"page":"2087-2100","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["The general probabilistic fuzzy set for modeling and its application in EMG robots"],"prefix":"10.1177","volume":"37","author":[{"given":"Wen-Jing","family":"Huang","sequence":"first","affiliation":[{"name":"School of Materials Science and Engineering, Central South University of Forestry and Technology, Changsha, China"},{"name":"School of Mechanical and Electrical Engineering, Central South University, Changsha, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi-Hua","family":"Li","sequence":"additional","affiliation":[{"name":"School of Traffic and Logistics, Central South University of Forestry and Technology, Changsha, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kang-Kang","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Electro-Mechanical Engineering, Guangdong University of Technology, Guangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2019,6,3]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0019-9958(65)90241-X"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/91.493904"},{"key":"e_1_3_3_4_2","unstructured":"DuboisD.
