Stabilizing uncertain steady states of some dynamical systems by means of proportional feedback

Nonlinear Analysis, 2013
A simple zero-order proportional feedback technique for stabilizing unknown fixed points is described. The technique employs either artificially created or natural stable fixed point to find the coordinates of the unknown unstable fixed point.
