PURPOSE: To suppress the medium noise of a magnetic circuit and to reduce energy loss by analyzing difference state equations by using the saddle point information of the chaotis movement of a magnetic wall in the magnetic circuit. CONSTITUTION: A chaos winding 5 for a chaos control is provided in an iron core 1 and a chaos control input μ (K) is inputted to the winding 5 by a chaos control circuit 6. The circuit 6 is previously inputted with saddle point vector information ζi and calculates the chaos control input μ (K) by an operation by obtaining the stationary vector ζ (K) of the magnetic wall at the time of a time K from the output of the secondary winding of a transformer as a chaos detection signal. The detecting of the state vector ζ (K) calculates the velocity V of the magnetic wall from the detection value e2 , e2 =nd /dt of the secondary winding 3 and the position X of the magnetic wall from the integration value of the voltage e2 . Since the effect of the chaos control having a stable magnetic wall is obtained at the time of K=50 and the energy loss of the transformer is ∫Kdx/dt.dx, the energy loss is reduced by the stablility of the magnetic wall.
