    在异步电机直接转矩控制中，磁链的观测是精确控制电机的一个重要环节.针对两类无速度传感器滑模观测器，从收敛性和参数敏感性两方面进行了深入的分析，并比较各自的优缺点.结合工程实际需要提出了一种混合型滑模磁链观测器算法.所提出的磁链观测器在控制中能消除初始磁链误差，又具有较好的鲁棒性.MATLAB仿真和实验结果论证了该方法的正确性和有效性.

    In DTC of induction motors,flux linkage observation is an important part of precise control of motor.The analyses from two aspects of convergence and parameter sensitivity were carried out herein in view of two kinds of speed sensorless sliding mode observer.The advantages and disad-vantages of two kinds of speed sensorless sliding mode observer were compared.A hybrid flux observ-er algorithm combined with the actual needs of engineering was proposed.The initial flux errors might be eliminated in the control of the new hybrid flux observer with good robustness.The correctness and effectiveness of the proposed method were verified by simulations and experiments.
