A　fault　detection　problem　of　networked　control　systems　with　quantized　measurements　is　discussed.　First,　a　separate　and　static　logarithmic　quantizer　for　each　output　is　modeled.　The　sector　bound　approach　is　used　to　describe　the　quantization　error.　Then　the　quantized　fault　detection　problem　is　transformed　into　the　fault　detection　problem　for　an　uncertain　system,　and　an　H-/H∞　fault　detection　system　is　designed　in　terms　of　linear　matrix　inequalities.　The　residuals　of　this　fault　detection　system　are　asymptotically　stable,　which　are　robust　against　uncertain　disturbances　and　sensitive　to　fault.　Finally,　a　numerical　example　is　provided　to　verify　that　the　quantization　error　decreases　the　fault　detection　system＇s　robustness　and　accurateness.　Furthermore,　the　simulation　result　demonstrates　the　validity　of　the　designed　fault　detection　system.
