Current change in the MR damper coil can change the stiffness and damping of the whole support system, so the vibration of high-speed rotor can be suppressed by the MR damper.
用这种阻尼器支承的磁悬浮轴承转子系统，通过控制磁流变阻尼器线圈中的电流来改变整个转子系统的支承刚度和阻尼，抑制转子高速时的振动。
The main idea of the control system is that PWM waves from DSP adjust outputting current from the current controller which can change the MR damper damp power.
该系统的思路是通过DSP输出PWM波形控制电流控制器的输出电流，从而实现调节磁流变阻尼器阻尼力的大小。
