In the existing research results, most of the complex systems are controlled in a certain direction, which leads to the disconnection between theoretical results and practical applications. The authors introduce unknown control coefficients, and the values of the upper and lower bounds of the control coefficients are generalized  by constants to allow arbitrary values to be arbitrarily large or arbitrarily small. In the control design program, the design problem of the controller is transformed into a parameter construction problem by introducing appropriate coordinate transformation. Moreover, we construct an output feedback practical tracking controller based on the dynamic and static phase combined by Ito stochastic differential theory and selection of appropriate design parameters, ensuring that the system tracking error can be made arbitrarily small after some large enough time. Finally, a simulation example is provided to illustrate the efficiency of the theoretical results.<\/jats:p>","DOI":"10.1155\/2020\/1502065","type":"journal-article","created":{"date-parts":[[2020,2,13]],"date-time":"2020-02-13T18:30:40Z","timestamp":1581618640000},"page":"1-8","source":"Crossref","is-referenced-by-count":4,"title":["Bounded Analysis and Practical Tracking Control of Complex Stochastic Nonlinear Systems with Unknown Control Coefficients"],"prefix":"10.1155","volume":"2020","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9063-547X","authenticated-orcid":true,"given":"Long-Chuan","family":"Guo","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, Hangzhou Dianzi University, Hangzhou 310018, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiang-Kun","family":"Fang","sequence":"additional","affiliation":[{"name":"Beijing Shougang International Engineering Technology Co.
