Abstract: A passivation control design procedure for linear time-invariant continuous systems is proposed. It
is shown that the Individual Channel Analysis and Design (ICAD) is an effective framework for the design of
multivariable passive control systems. The results presented are valid for the generalm×mcase but for the sake of
clarity two-input-two-output systems are considered. It is demonstrated that passivation can be achieved by: preor
post-compensation, feed-forward, and feedback. Working in the frequency domain, diagonal dominance can be
evaluated and thus appropriate input-output pairings can be defined. The influence of the non-diagonal elements of
the transfer matrix on the design of MIMO passive systems is clearly established. This fact is demonstrated through
the Multivariable Passive Function here introduced. The findings presented here are constructive, and a specific
set of examples has been created to illustrade the design process in detail. These examples are complemented
with the application to two real systems.
