New paper on A Characterization of Passivizing Input-Output Transformations of Nonlinear MIMO Systems!

This work extends our recent results on feedback passivation of SISO systems. Here, we extend our analysis to MIMO systems providing a characterization of all linear passivizing transformations for passive short systems. The MIMO formulation hints at embedding additional performance requirements on passivizing transformations establishing a link between optimal control design and passivation techniques.
