Abstract
An attitude adjustment device for placing the neutron monochromator which is the important component of the stress spectrometer is designed. It has the characteristics of large mechanical transmission ratio, diversified transmission modes and large load. Using the open-loop control system to drive the stepper motor has the problems of step loss and large mechanical transmission gap, and the positional positioning accuracy is difficult to guarantee; due to the influence of the mechanical transmission gap, friction and load inertia,using the closed-loop control system based on the PI control method will cause nonlinear natural vibration of the system; a composite closed-loop control method based on stepper motor is proposed, which improves the stability of the system, overcomes the mechanical transmission error, and improves the positioning accuracy.
