Problems solved by technology

However, in occasions that require high performance of the robot, this feedback control strategy will cause the robot to respond laggingly and reduce the trajectory accuracy, making it difficult to handle highly dynamic motion scenes, and the control parameters of the robot depend on the servo parameters. When the parameters are unreasonable Easy to cause mechanical vibration

Description

technical field [0001] The embodiments of the present invention relate to the field of industrial robot control, in particular to a robot motion control method, device, electronic equipment and media. Background technique [0002] In the field of industrial robot motion control, most controllers adopt servo three-loop feedback control strategy. This strategy sends the joint position information obtained by the interpolator directly to the servo position loop, compares it with the encoder feedback value, and uses the error value for control. However, in occasions that require high performance of the robot, this feedback control strategy will cause the robot to respond laggingly and reduce the trajectory accuracy, making it difficult to handle highly dynamic motion scenes, and the control parameters of the robot depend on the servo parameters. When the parameters are unreasonable It is easy to cause mechanical vibration. Contents of the invention [0003] Embodiments of th...
