碩士 === 國立雲林科技大學 === 電機工程系 === 103 === The main objective of this paper is used in the multi-axis machine platform developed mobile micro-stepping servo controller, although the advantage that can open loop stepper motor control positioning, but their efficiency, accuracy and jitter is obvious there is a gap, so this Papers made in micro-stepping the servo controller to improve its effectiveness and the amount of jitter, the drawback is the location of the optical encoder will be required to achieve feedback, this paper combined with point-and micro-step motion control servo controller technology in this Labs-developed digital control board for TMS320F28335 to achieve, but also taken into consideration when the application of the stepping motor in the environment are more limited occasions and limited hardware resources, such as: space, therefore bound to implement the TMS320F28335 technical studies how to integrate in a resource-constrained FPGA, and the matt encoder or position to control the current loop to improve the stability of rotation of the motor and the amount of jitter to improve research only under a feedback situation. Finally, point-to-point motion control combined with micro-stepping motor controller with load simulation parameter measurement and tabulation of nonlinear parameters to improve, but the situation improved for the step-out is quite limited, you may still need position feedback only way. It is divided into two parts, the first part mainly TMS320F28335 point-to-point motion control and micro stepping servo controller, and applied efficiency and the amount of jitter and the grant of non-position look back motor parameters to improve research, the second part of the main considerations hardware resources are limited and therefore how to implement it in a FPGA analyze the findings of the first part of the consolidation, and the ratio of the proposed method to save its resources.
