摘要： PROBLEM TO BE SOLVED: To provide a magnetic bearing control device that can prevent the deterioration of responsiveness at a magnetic bearing to a control signal and stably support a component to be supported.
SOLUTION: An H-bridge circuit is constituted of a coil 2c of an electromagnet 2b and four switches S1 to S4. A current is fed in one or the other direction with respect to the coil 2c arranged at the center of the H-bridge circuit by switching the switches S1 to S4 in accordance with the comparison result of a comparison circuit 8 that compares a control signal for position-controlling a rotating body 1 and a reference signal.

摘要： PURPOSE:To improve stability of control by performing electrification control for electromagnets, arranged in opposition to each other, on the basis of value of a gap and a bias current command or the like, in an opposition type control form magnetic bearing. CONSTITUTION:The captioned device makes two electromagnets 2-11 (22, 23). arranged in opposition to each other so as to hold a rotary body 1 (controlled body 21) between them, to float said body by means of their magnetic attractive force and support it, that is to say, each of electromagnet 22, 23 is controlled, to float and support the controlled body 21, through PID adjusting meter 25, electric current conversion parts 26, 27 according to deviation between a target gap x0 and a detected gap x1 from a gap detector 24. At this time, the value obtained, through multiplying by gap x1 the sum of output I0 of PID adjusting meter 25 and a bias current command Ib from a commander 35 by means of multipliers 33, 34, is inputted to the current converter 26, while the value obtained, through multiplying by gap X2, the balance after subtracting command Ib from command I0 is inputted to the current converter 27.
摘要翻译：目的：为了提高控制的稳定性，以对置型控制方式的磁轴承为基础，通过对间隙和偏置电流指令等进行对置配置的电磁铁进行电气化控制。构成：标题装置使两个电磁铁2-11（22,23）。彼此相对设置以便在它们之间保持旋转体1（受控体21），以通过它们的磁吸引力使所述主体浮起并支撑它，也就是说，每个电磁体22,23被控制通过PID调节仪25，电流转换部26,27，根据目标间隙x0与从间隙检测器24检测到的间隙x1之间的偏差来浮动并支撑受控体21.此时，通过乘以间隙x1，通过乘法器33,34将PID调节计25的输出I0和来自指令器35的偏置电流指令Ib的和输入到电流转换器26，而通过乘以间隙获得的值 X2，从指令I0减去指令Ib之后的余额被输入到电流转换器27。
