This methods uses LMI techniques iteratively to obtain the result.
Given a state-space representation of a system and an initial estimate of reduced order model .
Where and .
The full order state matrices .
The objective of the optimization is to reduce the norm .
The LMI: The Lyapunov Inequality[edit | edit source]
The LMI techniques results in model reduction close to the theoretical bounds.
A list of references documenting and validating the LMI.
