摘要
在异步电机矢量控制电流环中采用参数自适应PID算法。该算法采用带遗忘因子的递推最小二乘算法对PID参数进行在线估计,能够根据不同情况实时调整PID参数。试验结果表明,该算法鲁棒性强、稳定性好、自适应性强、计算量小,能够满足对电流控制的要求,并且提高了速度的抗干扰能力。
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 real-time 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 anti-interference ability of the speed.
