Parameter　uncertainty　and　measuring　noise　are　still　very　challenging　work　in　developing　an　appropriate　controller　for　the　automated　clutch　system　due　to　the　effect　of　the　external　disturbances.　This　paper　introduces　a　robust　control　method　for　automated　clutch　system.　A　nonlinear　dynamic　model　for　the　screw-nut　actuator　associated　with　clutch　is　derived,　and　then　a　dynamic　sliding　mode　controller　for　automated　clutch　of　AMT　vehicle　is　presented.　The　chattering　phenomenon　is　alleviated　and　the　robustness　is　improved　by　adopting　the　proposed　controller.　Based　on　dSPACE　and　Matlab/Simulink,　the　rapid　control　prototyping　(RCP)　of　automated　clutch　is　used　to　demonstrate　the　efficiency　and　robustness　of　the　proposed　algorithm　via　the　comparison　with　both　the　PID　controller　and　the　conventional　sliding　mode　controller　(CSMC).　©　2010　IEEE.
