对微振动隔离系统提出了三个性能要求：(1)与地面振动隔离；(2)抑制直接振动；(3)稳定定位。在应用传统的无源技术和反馈控制的有源技术时，这些要求存在一定的权衡关系。为了获得较高的性能并突破权衡限制，提出了一种具有前馈控制的双主动控制方法。前馈控制对于消除干扰和定位被控对象是有效的。因此，这种控制方法实现了隔离器的所有三个要求。实验结果表明了所提控制方案的有效性。
On microvibration isolation systems, three performance requirements are imposed : ( 1 ) isolation from ground vibration, ( 2 ) suppression of direct vibration, and ( 3 ) stabilized positioning. These requirements have some trade-off relationships when are applied conventional passive technologies or feedback-controlled active technologies. In order to obtain high performance and to break through the trade-off limitations, a double-active control method with feedforward control is proposed. Feedforward control is effective for cancelling disturbances and for positioning the controlled object. Thus, this control method realizes all three requirements for the isolator. Experimental results show the usefulness of the proposed control scheme.
