Problems solved by technology

Among them, the servo motor will generate cumulative error when it performs periodic motion in one direction. If the cumulative error is not corrected in time, it will affect the subsequent positioning accuracy, and then affect the motion track of the motion simulator, resulting in the virtual environment presented by the VR system. Incompatible with the operation of motion simulators, which degrades the passenger's virtual experience

Abstract

The invention discloses a PLC-based servo motion control system, method and VR equipment, relates to the technical field of servo control, and can regularly correct the cumulative error generated by the servo motor to improve its positioning accuracy. The system includes a control unit, a main servo driver, an auxiliary servo driver, a main shaft servo motor, an auxiliary shaft servo motor, and a distance measuring unit. The main shaft servo motor is used to upload the real-time encoded position information of the encoder to the control unit; The real-time detection position information of the spindle servo motor is uploaded to the control unit; the control unit is used to calculate the difference between the encoded position information and the detection position information at the same time in real time, and when the difference exceeds the threshold, the corresponding detection position information is marked, and in the next Before the movement cycle, the detected position information of the mark is written into the encoder as the corresponding encoded position information.

Description

technical field [0001] The invention relates to the technical field of servo control, in particular to a PLC-based servo motion control system, method and VR equipment. Background technique [0002] VR equipment usually consists of two parts: a VR system and a motion simulator. While experiencing the virtual environment through the VR system, passengers can feel the motion experience that matches the current virtual environment through the motion simulator. [0003] The motion simulator is mainly composed of a servo motor and a control unit that outputs control commands. Among them, the servo motor will generate cumulative error when it performs periodic motion in one direction. If the cumulative error is not corrected in time, it will affect the subsequent positioning accuracy, and then affect the motion track of the motion simulator, resulting in the virtual environment presented by the VR system. Incompatible with the operation of motion simulators, which degrades the pa...
