Abstract

The invention relates to a synchronous control method and track tracking of an annular coupling type multi-axis robot system based on a self-adaptive fuzzy PID. Before the position controller operates, the PID parameters by adopting a self-setting method is set, and based on the self-adaptive fuzzy PID method, a multi-axis robot trajectory tracking controller is designed; and a multi-axis robot synchronous controller is designed on the basis of an annular coupling type control method. The synchronous control method can effectively improve the synchronous control problem of the multi-axis robotsystem, the fast convergence performance of the system is improved, and the track tracking precision of the multi-axis robot system is enhanced.

Description

technical field [0001] The invention belongs to the field of multi-axis robot control, and relates to a synchronous control method of a ring-coupled multi-axis robot system, in particular to the synchronous control and tracking control of a multi-axis robot system with uncertain control parameters and complex structure. Background technique [0002] The robot system is a highly complex system with strong nonlinearity and strong coupling. It has the characteristics of multiple input and multiple output, and there are many uncertainties and factors that are not conducive to the improvement of system performance. Nowadays, robots in industry are often used in arc welding, cutting, assembly and other occasions that require extremely high trajectory tracking and running stability. The requirements for the robot's maximum working speed, acceleration, trajectory accuracy and other performance indicators are getting higher and higher. Most industrial robots use independent joint con...
