摘要
保偏光纤自动定轴技术涉及光纤位置、姿态的精确定位、检测和调整,对光纤位置、姿态实时精确的调整提出了较高的要求。设计并实现了一种用于保偏光纤自动定轴的多轴步进电机细分驱动控制电路。该电路以TI公司的DSP2812为控制系统核心构架,采用DRV8846作为功率级驱动芯片,在研究步进电机控制和细分驱动原理基础上,对电流细分和自动衰减模式方案进行了设计,有效抑制电机运动过程中的噪声和机械振动,改善低频振荡、高频失步等现象,在提高步进电机运动性能的同时,实现了系统的小型化。
The automatic fixed axis technology of the PMF involved precise positioning,testing and adjustment of optical fibers' position and posture,putting forward higher requirements for the precise adjustment of optical fiber position and orientation in real time. Designed and implemented multi-axis stepper motor subdivision driver control circuit used to the automatic fixed axis of PMF. The circuit took TI's DSP2812 as the control system core architecture,using DRV8846 as a power stage driver chips, designing the scheme of current decay mode and automatic segmentation based on the study of stepper motor control and segmentation drive the principle. It effectively inhibited the noise and mechanical vibration in the movement of the motor,improving low-frequency vibration,high-frequency step-out,and to enhance the sports performance of the stepper motor.
