Abstract

The invention discloses a fuzzy active disturbance rejection control method of a permanent magnet synchronous motor used for industrial robots. The method comprises the following steps: collecting the rotor position signals of a motor servo system, then using the rotor position signals as the feedback signals of an active disturbance rejection controller, using a fuzzy inference rule, establishing a fuzzy rule control table, and realizing high precision control for the motor servo system through automatic adjustment of parameters and compensation for system disturbance. A traditional vector-controlled PI adjustment method is replaced by using the fuzzy active disturbance rejection control method, the rapidity and stability of a driving system of the permanent magnet synchronous motor used for industrial robots are improved, and the precision and disturbance rejection capacity of the system are improved.

Description

technical field [0001] The invention belongs to the technical field of industrial robot servo motor design, and in particular relates to a fuzzy active disturbance rejection control method for a permanent magnet synchronous motor used in an industrial robot. Background technique [0002] In recent years, with the continuous advancement of the Made in China 2025 strategy, in the process of transformation and upgrading of my country's manufacturing industry, the phenomenon of machine substitution has become more and more popular, and the application of industrial robots has become more and more extensive. At present, in terms of the performance of industrial robot servo systems The dynamic response ability is poor, and most of them only have analog and pulse control methods, which cannot meet the requirements of high-speed and high-precision robots. Therefore, it is very necessary to design an AC servo drive system for industrial robots. [0003] The permanent magnet synchronou...
