摘要：
The delayed feedback control method proposed by Pyragas is practically useful for control of chaos. Conditions for (local) stabilization by the delayed feedback, however, are more restricted than those by the OGY method. In order to overcome this problem, we proposed a delayed feedback control method using nonlinear estimation of stabilized orbits. Moreover, we give several conditions for stabilization by the proposed method, using robust control theory and linear matrix inequalities. (C) 1998 Elsevier Science B.V.
