A new solution to the induced l_∞ finite impulse response filtering problem based on two matrix inequalities

摘要

In this paper,we use an induced l_∞ approach to create a newfilterwith a finite impulse response (FIR) structure for state-space models with external disturbances. This filter is called an induced l_∞ FIR filter (ILIFF). The proposed ILIFF's gain matrix can be determined by solving a linear matrix inequality problem for a fixed positive scalar variable. An illustrative example is given to demonstrate the effectiveness of the ILIFF.
