Abstract
Recently, the methods for controlling chaos, in which OGY method is famous, are proposed. Many of them can acheive the linear control in the region near the unstable periodic points locally. In this paper, the delayed feedback control method, which is proposed by Pyragas for the continuous system, are applied to control the magneto-elastic chaos and stabilize the unstable periodic orbital in them experimentally. In addition the analogy between the system and the metal cutting dynamics are discussed. The discussion will show the system in consideration has the wide physical meaning.
