碩士 === 聖約翰科技大學 === 自動化及機電整合研究所 === 94 === In this thesis, the motion controller is implemented by the 8052 micro-controller and FPGA-based controller, respectively. The design system consists of three parts. There are 3-axis motion platform, motion controller and personal computer. Three two-phase stepping motors derive the 3-axis motion platform. Program design in computer includes user interface design, the computation of moving path coordination, the definition of data format and the setup of serial transmission. The motion controller comprises of 8052 micro-controller, memory design, peripheral decoder and current driving circuits. A quite good motion resolution is obtained in this design. It has one-step movement resolution in all design function. Moreover, a FPGA-based controller is also design. The NIOS-embedded microprocessor is used to calculate the moving path coordination and process the user interface. It can reduce the cost and simplify the hardware design by using FPGA-based design.
