A Residual Approach for Balanced Truncation Model Reduction (BTMR) of Compartmental Systems
William La Cruz
This paper presents a residual approach of the square root balanced truncation algorithm for model order reduction of continuous, linear and time-invariante compartmental systems. Specifically, the new approach uses a residual method to approximate the controllability and observability gramians, whose resolution is an essential step of the square root balanced truncation algorithm, that requires a great computational cost. Numerical experiences are included to highlight the efficacy of the proposed approach.
Keywords: model reduction; Lyapunov equation; compartmental systems.
