基于加速度扰动观测器的卡尔曼观测器弧形电机低速控制

This article proposes a novel speed measurement strategy for a permanent magnet arc motor (arc motor) servo system. This method improves the accuracy of a low-resolution encoder at low-speed condition through a newly developed acceleration-based disturbance observer (ADOB) combined with a Kalman observer (ADOB-KMO). A novel model-reference-adaptive inertia identification based on position signal i...
