Multi-mode control switching method for robot servo system

The invention discloses a multi-mode control switching method for a robot servo system, relates to the technical field of control switching, and is used for solving the problem that the control quantity received by an execution layer at the moment of control mode switching is discontinuous. Collecting a control instruction output frequency of a current control mode controller, calculating an output stability factor based on an output frequency sequence, and when the output stability is insufficient, introducing a log write-in proportion of a control software operation level and calculating a phase jitter density; the mode switching process is subjected to conjoint analysis from the two sides of control output behavior and software state activity, the switching impact time delay is calculated by combining the historical instantaneous switching behavior characteristics of the mode to be switched and the amplitude limiting trigger duration of the controller, the default transition duration interval is subjected to targeted adjustment, and the mode switching time delay is calculated. And the mode switching smoothness and the operation reliability in a complex operation scene are improved.

A multi-mode control switching method for a robot servo system

This invention discloses a multi-mode control switching method for robot servo systems, relating to the field of control switching technology. It addresses the problem of discontinuous control quantities received by the execution layer during control mode switching. By identifying that the robot is in a control mode switching state, the method collects the output frequency of the controller's control commands for the current control mode and calculates an output stability factor based on the output frequency sequence. When output stability is insufficient, it introduces the log writing ratio at the control software runtime level and calculates the phase jitter density. The method jointly analyzes the mode switching process from two perspectives: control output behavior and software state activity. Combining the historical instantaneous switching behavior characteristics of the mode to be switched with the controller's limiting trigger duration, it calculates the switching impact delay and adjusts the default transition duration range accordingly, improving the smoothness and reliability of mode switching in complex operating scenarios.
