| 摘 要： | 将自适应逆控制应用干异步电机变频调速控制，对给定信号、参数摄动和外部扰动分别施以控制，使二者同时达到最佳控制效果，无需在二者之间进行折衷．利用变论域变步长的LMS自适应滤波算法，使自适应逆控制的异步电机变频调速系统及其逆系统辨识的初始收敛速度、时变系统跟踪能力及稳态精度3个指标同时达到最优．仿真实验表明了该控制的先进性和有效性．

| Abstract: | Adaptive inverse control is applied to the variable frequency speed regulation of asynchronous motor. The reference signal and the disturbance signal are controlled, which can achieve optimal effect in the meantime. Applying adaptive LMS algorithm based on variable step and variable region to variable frequency speed regulation system, the initial convergence rate, tricking ability of time-varying system and stable precision are best in the meantime. The simulation result shows the advantage and the effectiveness of the adaptive inverse control. |
