摘要

对扭转控制器进行了自适应,减小了控制的不连续幅度。二阶实滑模是稳定地保持的,这是由于在检测到散度的时刻,增益与选定的常数因子瞬间相乘。然后增益逐渐减小。所得增益最大值不超过未知等效控制幅度乘以某一因子。计算机模拟证实了理论结果。

Twisting-controller gain adaptation
Adaptation of twisting controller is performed in order to diminish the discontinuous control magnitude. The second-order real sliding mode is stably kept due to the instant multiplication of the gain by a chosen constant factor at the moments when the divergence is detected. Then the gain is gradually decreased. The resulting gain maxima are proved not to exceed the unknown equivalent control magnitude multiplied by a certain factor. Computer simulation confirms the theoretical results.
