| 摘 要： | 电磁轴承系统的控制策略按被控的物理可分为电压控制和电流控制。文章研究了选用何种策略可与功放电路的类型紧密相关，通常所用的功放电路均为电压－电压功率放大电路，这种电路仅适用于电压控制策略，通过分析这两类控制策略之间的差异和特点，文章介绍一种适合于电流控制策略的电压－电流功率放大电路。

| Abstract: | There are twokinds of control strategy for electromagnetic bearing system(EMBS),voltage control strategy(VCS)and current control strategy(CCS),according to the regulat-ed physical varible,which on selected for analysis of the system is closely related to the typeof power amplifier.Commonly used power amplifier is usually a voltage-to-voltage amplifierthat is only suited for the VCS.After discussing the differences between VCS and CCS,thispaper introduces a method of design of voltage-to-current power amplifier that is suited forCCS. |
