| Summary: | 碩士 === 長庚大學 === 電機工程研究所 === 93 === Recently, linear motors have been widely applied in versatile high-tech industries. These achievements are primary based on the high-precision position control. Due to the merits of large force, high efficiency, and easy of position control, the applications of linear permanent magnet synchronous motors (LPMSM) have become much more popular. The goal of this thesis is to realize a high-speed position control platform of LPMSM. In the stage of controller design, based on linear matrix inequalities, both Lyapunov theorem and fuzzy-scheduling control method are incorporated such that the nonlinear motor system can still have fast responses, even with possible change of load. In general, PC-based control systems have drawbacks in system synchronicity, analog and digital grounding drift, and complicated wiring. Thus, in this thesis, to evaluate the control performance, a DSP/FPGA based experimental platform of LPMSM is setup. Simulation and experimental results illustrate that the proposed control scheme does provide the ability of high-precision position control.
