PURPOSE:To prevent the deterioration of the control performance generated near the response frequency of a rotary motion control system by compensating the gyroscopic effect at the time of high-speed rotation via a cross feedback in an active control type magnetic bearing device. CONSTITUTION:In a control device with two degrees of freedom for rotary motion, the thetax rotary displacement signal of a rotary shaft outputted from a thetax arithmetic circuit 42 is fed to a low-pass filter 47 with the crossover frequency equal to or lower than the response frequency of a rotary motion control system and is multiplied by the gain, it is added to the thetay control signal outputted from a compensating circuit 40 by an adder 41, and it is outputted as the current command ithetay. The thetax current command ithetax is outputted in the same way. |
