Abstract

The invention discloses a turntable control system and a turntable control method, the turntable control system comprises a control module, a detection module and an execution module, and the detection module and the execution module are respectively connected with the control module; the control module comprises a DSP processor and a single-chip microcomputer. The DSP is used for receiving a turntable control instruction; the DSP processor is electrically connected with an A/D converter; the A/D converter is electrically connected with the execution module; the execution module drives a turntable to rotate, a dual-port SRAM serving as a shared memory is arranged between the single-chip microcomputer and the DSP, two ports of the dual-port SRAM are respectively connected with the DSP and the single-chip microcomputer, and the single-chip microcomputer is electrically connected with a display. The turntable can quickly and stably reach a given position, and the control precision of theturntable is ensured.

Description

technical field [0001] The invention belongs to the technical field of industrial control, and in particular relates to a turntable control system and a control method thereof. Background technique [0002] In the field of numerical control, it is necessary to precisely control the number of turns and the angle of the turntable movement. However, during the high-speed rotation of the turntable, due to motion inertia and other reasons, the position control of the turntable cannot meet the requirements of precise product processing. That is to say, for the movement of the turntable, the angle offset is caused by the braking distance, the control precision is not enough, and the corresponding control effect cannot be achieved. [0003] In the prior art, the photoelectric encoder is used to feed back the position information of the turntable in real time, thereby realizing the closed-loop control of the turntable, thereby improving the accuracy of the position control of the tu...
