碩士 === 國立虎尾科技大學 === 自動化工程研究所 === 101 === This thesis is to develop a digital control system for a multi-axis motion platform which is mainly based on programmable logic controller(PLC) and servo controller. This study completion of development a multi-axis motion platform controller and feedback system information. In addition, the study designed a servo control system for a linear motor based on sliding mode and fuzzy logic control, and to design a novel exact-status-estimator fuzzy logic control strategy. By creating a linear motor dynamic model, the sliding mode control, adaptive sliding mode control. Furthermore, a fuzzy sliding mode control and a fuzzy control are designed with a novel exact-estimator. This ovel control strategy can ignore that system parameter, and sliding mode control of the robust control selection problem by fuzzy logic. The control system in this stability provided by Lyapunov stability, and verified by simulation and experimental result.
