Due to the characteristic of non-linear dynamic, time-delays, external disturbance and parameter uncertainty, the automated clutch is difficult to be controlled precisely. A sliding mode controller was introduced to control the automated clutch effectively. The sliding and global stability conditions were formulated and analyzed in terms of Lyapunov full quadratic form. The rapid control prototyping of automated clutch was built based on dSPACE. The experiment results show the controller is effective and robust to the parametric variation and external disturbance.
