| Summary: | 碩士 === 國立臺灣大學 === 機械工程學研究所 === 91 === It is desirable in the high performance servo design to be able to carry out the design and testing without actually having to construct a prototype system. This is especially true in the design of machine tool servo where building a prototype system is very expensive. However, the very complicate machine structure and the nonlinear effects have made very difficult to carry out the design without a suitable model.
Notice that the recent software advances has allowed very accurate dynamic simulation results and it is possible to integrate the control synthesis with the dynamic simulation. This research thus tries to examine the effects of carrying out the servo design within the simulation environment. The robust sliding mode controller is employed to deal with the nonlinear characteristics in the precision machine tool servo system. The dynamic model included the multi-degree-of-freedom behavior and the friction effects. The sliding model controller is able to suppress the structure resonances and achieve high accuracy control under plant uncertainties.
