英文摘要：

Five - degree freedom magnetic bearings is a multiple inputs multiple outputs system. The realization of expectation precision, stiffness and stability depend on control system hardware design. The complex arithmetic succeeds by high speed floating digital signals processing unit. High speed and precision A/D can help sampling in reason. The sensors and power amplifier is also important aspect. The test has shown that the design meets the requirements of stability and high precision,the setting time is fast.
