碩士 === 修平技術學院 === 電機工程研究所 === 99 === The design principle of sliding mode control is to use the switching controller to force the system state trajectory into the sliding surface and converge to zero or reach the target point. Sliding mode control is a well-known and robust approach which can control the overall system with undergoing system uncertainties and external disturbances. In this thesis, the Active Engine Mounting (AEM) system to isolate vehicle engine body vibration by utilizing Sliding Mode Control (SMC) and generalized projective synchronization for Horizontal Platform Systems (HPS) via Nonsingular Terminal Sliding Mode Control (NTSMC) are discussed. The NTSMC used here not only keep the performance of high speed of sliding while near the equilibrium state, but get the guarantee of finite time convergence under the design of dynamic nonlinear sliding surface also. The simulations show, the trajectory of state can be tracked completely during a finite time while the system state trajectories reach the sliding surface. Moreover, the vibration of AEM system can be isolate and withstand different type of disturbances and the chattering effect has been avoided with the NTSMC proposed.
