Abstract

Abstract

An automation control system for the optical path is proposed in this paper, based on the MC9S12XEP100 core controller, to realize automatic control of the optical path of the laser Raman spectrometer. A closed-loop control algorithm based on the pressure sensor is proposed to address problems such as low precision, easy "lost step, " and "blocked rotor" in open-loop motor control. This algorithm greatly improves the control accuracy and system stability and effectively avoids the problem of motor blocking. Experimental results show that the control system can realize the functions of arbitrary adjustment of multi-path light, access and reset of light path, closed-loop self-check, and host computer communication. The displacement error accuracy controlled by this system is within 0.1mm, which meets the basic requirements of stability, reliability, high precision, and strong anti-interference ability in the optical path control system.
- optical path automation control,
- stepper motor,
- closed-loop self-check
