Abstract :
Balanced truncation is one of the most popular techniques in model reduction and was first proposed by Moore (1981) for linear continuous systems. The technique is based on finding a balanced realization of the system and truncating the least controllable and observable states to find the reduced order model. The technique was extended to the reduction of discrete systems in Pernebo and Silverman (1982). In Schelfhout and De Moor (1995), a time-weighted balanced truncation method was presented for obtaining the reduced-order models. In this paper, we present the frequency response error bounds for their technique.
