Abstract

The invention belongs to the technical field of an analog-digital hybrid circuit and specifically relates to a single-axis rotation mechanism control circuit. The circuit comprises a power supply filtering and adjustment module, a central processor module, a control module, a motor interface, a computer serial communication module, an optical coded disc serial communication module and a clock. Accurate angle measuring circuit angle can be obtained at regular time through the rotation control circuit; a control system drives a motor through a digital-analog converter; and the control system, the motor and an angle measuring circuit form a complete motion control system. According to the technical scheme, the rotation mechanism control circuit realizes a function of control of rotation speed and position of a rotation mechanism, has a power-on self-test function and a patrol detection function in the working process, overcomes the problems of electromagnetic compatibility and power consumption and realizes obvious improvement of movement characteristics of the rotation mechanism.

Description

technical field [0001] The invention belongs to the technical field of analog-digital hybrid circuits, and in particular relates to a single-axis rotating mechanism control circuit. Background technique [0002] In the case of increasing the cost of improving the accuracy of inertial devices, using error self-compensation technology to improve the positioning accuracy of inertial navigation systems is a major direction for the development of inertial technology. [0003] The single-axis rotating inertial measurement component performs alternate reciprocating motion around the azimuth axis under the control of the rotating mechanism. The navigation software completes the navigation calculation under the simultaneous action of the alternating reciprocating motion and the actual motion of the carrier, and through the rotation demodulation, in the output navigation information The alternate reciprocating indexing motion is removed, and the actual motion information of the carrie...
