This　paper　examines　an　l2　−　l∞　filtering　problem　for　a　class　of　discretetime　networked　switched　systems　with　multiple　packet　dropouts,　while　the　data　packets　include　both　the　measurement　output　signal　and　the　switching　signal.　The　multiple　packet　dropouts　phenomenon　is　described　by　Bernoulli　binary　sequences　with　known　probabilities.　Then,　by　constructing　a　novel　switched　Lyapunov　function　with　the　random　missing　of　switching　signal　taken　into　account,　a　switched　filter　is　designed　such　that　the　filtering　error　system　is　exponentially　stable　and　satisfies　the　l2−l∞　disturbance　attenuation　level.　The　parameters　of　the　filter　are　obtained　by　solving　an　LMI.　Finally,　a　practical　example　is　presented　to　verify　the　effectiveness　of　the　proposed　approach.　©　2020　ICIC　International.
