PROBLEM TO BE SOLVED: To provide a magnetic bearing control device which simplifies arithmetic processing and realizes multiple input and multiple output robust control suitable for central control of a plurality of magnetic bearings.;SOLUTION: A first mathematical model of a detailed control target 20 comprising an actuator 21, a rotary body 1, an amplifier 22 and a position sensor 23 is derived. An order reduction of the first mathematical model is performed, and a second mathematical model of an enlarged control target Ga(s) comprising a PI control section 13, a subtracter 14, a PD control section 15 and the detailed control target 20 is derived by using the order-reduced first mathematical model. The order of the second mathematical model is set to be low, and an expression is derived by employing a loop shaping method for the second mathematical model. The robust control is performed according to the expression.;COPYRIGHT: (C)2007,JPO&INPIT
