Publicacions matemàtiques, 41 (1), 181-198.0214-1493http://hdl.handle.net/11441/58677Symmetric piecewise linear bi-dimensional systems are very common in control engineering. They constitute a class of non-differentiable vector fields for which classical Hopf bifurcation theorems are not applicable. For such systems, sufficient and necessary conditions for bifurcation of a limit cycle from the periodic orbit at infinity are given.application/pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Hopf bifurcation theoremsControl engineeringVector fieldsinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess
