Finite-Frequency Model Order Reduction of Linear Systems via Parameterized Frequency-dependent Balanced Truncation
Balanced truncation is the most commonly used model order reduction scheme in control engineering. This is due to its favorable properties of automatic stability preservation and the existence of a computable error bound, enabling the adaption of the reduced model order to a specified tolerance. It aims at minimizing the worst case error of the frequency response over the full infinite frequenc...
متن کاملBalanced truncation model reduction of periodic systems
The balanced truncation approach to model reduction is considered for linear discrete-time periodic systems with time-varying dimensions. Stability of the reduced model is proved and a guaranteed additive bound is derived for the approximation error. These results represent generalizations of the corresponding ones for standard discrete-time systems. Two numerically reliable methods to compute ...
متن کاملPassivity-Preserving Balanced Truncation Model Reduction of Circuit Equations
We consider passivity-preserving model reduction of circuit equations using the bounded real balanced truncation method applied to a Moebius-transformed system. This method is based on balancing the solutions of the projected Lur’e or Riccati matrix equations. We also discuss their numerical solution exploiting the underlying structure of circuit equations. A numerical example is given.
متن کاملModel Order Reduction of Large Circuits Using Balanced Truncation
A method is introduced for model order reduction of large circuits extracted from layout. The algorithm, which is based on balanced realization, can be used for reducing the order of circuits before circuit-level simulation. In contrast to Padebased algorithms which match the reduced order system with original system in some given frequencies, balanced realization based model algorithms provide...
متن کاملBalanced Truncation Method of Model Order Reduction on Tidsp
Thesimulation and analysis of large complex systems,have become easier by using model reduction technique. In thispaper, the authorsutilized Balanced Truncation (BT) method of modelreduction and is found to be competitive to other Model Order Reduction(MOR) approaches.Further, the same is implemented on Texas Instruments’ TMS320C54xxprocessor. The suitability of the method is illustrated by sol...
