Linear and Nonlinear control methods are being applied to ever more complex and higher dimensional systems. Therefore
there is a great need for reduced order models that capture the essence of the control system in a lower dimensional setting.
The goal is to find reduced order models that are analytically and computationally tractable. Moreover the reduction method
should be well motivated and computationally feasible.
In 1981, Moore introduced linear balanced truncation and this work has been extended in many ways to both linear and
nonlinear systems. We shall review this and describe our recent extension based on the concept of input normal forms.
The method shall be applied to a nonlinear model of a multi-link assemblage.
