PURPOSE:To secure the compensation at a high speed even to a nonlinear element by using the disturbance estimating compensation control in addition to the non-interference shortest time control method for a system which can be expressed in the primary process by the non-interference. CONSTITUTION:This method is applied to control a poloidal magnetic field coil current with a tokamak equipment and this magnetic field coil have a function to produce the plasma and control the position and the form of the plasma. An equivalent circuit 1 is shown in the figure together with an equivalent circuit 2 of each magnetic field coil, magnetic field coil resistances R1-Rn, self-inductances L1-Ln of the magnetic field coil, magnetic field coil currents I1-In, a plasma current Ip, etc. Then the electromotive force induced to each magnetic field coil by the current Ip is regarded as the disturbance through the control of currents of plural magnetic field coils having mutual induction and by the non-interference shortest time control method. The method for estimation and compensation of disturbance is also applied. Thus the magnetic field coils are controlled independently of each other with high accuracy.
