H ∞ switching filter design for LPV systems in finite frequency domain

A Finite Frequency Approach to H∞ Filtering for T–S Fuzzy Systems with Unknown Inputs

“…Indeed, several forms of fault detection observers are introduced using H − ∕H ∞ performance indices [15][16][17]. Other attempts considered H ∞ filtering for uncertain linear systems [18,19], state delayed systems [20,21] and for switching linear parameter varying systems [22,23]. Design conditions are generally given in LMI formulation.…”
