Problems solved by technology

When the traditional motor drive control method is applied to this type of rail vehicle, there are the following problems: Whether the left and right drive wheels are driven by the same motor through the differential transmission mechanism, or are driven independently by two motors, there will be mutual competition between the wheels on both sides The problem——that is, the relative motion state between the left and right wheels and the track is inconsistent, which eventually leads to the situation that the vehicle is unstable or even unable to walk normally, which seriously affects the detection work.

Abstract

The invention discloses a dual-servo motor control method for a track detection device of an amusement facility. Two motors are used to respectively drive the drive wheels on the left and right sides, wherein the first servo motor is the master, the second servo motor is the slave, and the second servo motor works In the torque mode, adjust the output torque of the servo motor 2 according to the current feedback value of the servo motor 1, so that the current feedback values ​​of the two are close to each other, so as to ensure that the working states of the two are similar, and avoid the close situation between the two. The structure is simple, the response speed is fast, the reliability is high, and the flexibility is good. It can effectively and stably control the running of the track detection device of the amusement facility, and better realize the comprehensive detection of the track by the track detection device of the amusement facility.

Description

technical field [0001] The invention relates to a control method of a servo motor, in particular to a method for controlling a double servo motor in a track detection device of an amusement facility. Background technique [0002] The track inspection device of amusement facilities realizes the functions of macroscopic inspection, wall thickness inspection and crack inspection of the track of amusement facilities by carrying cameras, ultrasonic thickness gauges, eddy current flaw detectors and other inspection instruments on the vehicles walking along the facility rails. [0003] The track of the amusement facility is usually two groups in parallel, and the left and right driving wheels of the vehicle travel along the track on the corresponding side respectively. When the traditional motor drive control method is applied to this type of rail vehicle, there are the following problems: Whether the left and right drive wheels are driven by the same motor through the differential...
