  A novel delayed feedback control based on full state is proposed. The
designed scheme combines the difference between two delayed states and a
periodic control gain. System stabilization is achieved in any hyperbolic
unstable equilibrium point. The procedure to build the control is systematic
and, the set of the stabilizing control parameters is rigorously featured by
analytical arguments. An ad-hoc strategy based on the proposed scheme is
implemented for control of chaos by stabilizing equilibrium points embedded in
chaotic attractors. Simulated examples illustrate this strategy performance.
