ROSAS ALMEIDA, D.I.  y  ALVAREZ, J.. Condiciones para la existencia de una bifurcación Hopf en la estructura de control con modelo interno. Rev. mex. fis. [online]. 2007, vol.53, n.6, pp.481-487. ISSN 0035-001X.

We present sufficient conditions for the existence of a Hopf bifurcation in the internal model control structure. We present also an experimental illustration using an analogical electronic circuit that satisfies these conditions. The results can be used in the design of oscillator.
