This paper describes a novel reformulation of a classical active vibration isolation problem explicitly accounting for the dynamics of the actuator. By utilizing a clever reformation of the problem rather than the traditional approaches, a very difficult problem can be transformed into a relatively easy one. Subsequently, any reasonable loop closure methodology can be used to achieve the necessary performance. The traditional approaches usually consider a regulation problem, whereas the focus here will be on generating a tracking problem to achieve the same results: reduced transmission of vibration. Experimental results are included to demonstrate the effectiveness and advantages of the proposed problem representation.
