| Abstract: | Used parameters adaptive PID algorithm on the current loop of the asynchronous motor vector control. This algorithm adopts the recursive least square method with forgetting factor to estimate the PID parameters online. Can realtime adjust PID parameters according to different situations. The experimental results showed that this algorithm was good robustness, stability, strong adaptability, small amount of calculation and could meet the requirement of current control, and improve the antiinterference ability of the speed. |
