An electronic control device for a single-axis speed and double-axis position turntable

Abstract

The invention relates to inertial device testing equipment technology, in particular to an electric control device for a single-axis rate and double-axis position turntable, including: a pitch axis encoder, an IK220 counter card, a spindle encoder, an IBV660B interpolator, a DSP motion control system, The drive, spindle motor, real-time angle position display module and ISA bus, the analog signal generated by the pitch axis encoder, after being processed by the IK220 counter card, is read by the real-time angle display module for the interface display of the real-time angle position of the pitch axis, The analog signal generated by the spindle encoder is processed by the IBV660B interpolator and then sent to the DSP motion control system. One of them is read by the real-time angle position display module and displayed on the interface, and the other is processed to generate a servo analog signal and sent to the driver. The driver drives the motor to rotate, and at the same time meets the needs of position display and servo drive motor.

Description

technical field [0001] The invention relates to the technical field of inertial device testing equipment, in particular to an electric control device for a single-axis rate and double-axis position turntable. Background technique [0002] The dual-axis turntable is a kind of inertial device testing equipment with two degrees of freedom of rotation, which is used for the rate and position function test of the two degrees of freedom of motion of inertial devices. Generally speaking, a two-axis turntable includes a main shaft capable of horizontal movement and a pitch axis capable of pitch movement. Both the main shaft and the pitch axis are driven by motors, and photoelectric encoders are used to collect and feed back the real-time motion positions, forming a double closed-loop electrical system. control structure mode to ensure the realization of the speed motion and position motion functions of the main shaft and pitch axis.

Problems solved by technology

[0004] However, the encoder signal in the existing dual-axis turntable with single-axis rate and double-axis position function is only subdivided by a low-multiplier subdivider, so its angular position resolution cannot meet the requirements of high-precision turntables, and the control The load of the system is relatively large, and the electronic control structure is complex
