摘要：
无轴传感器的电动驱动控制已是一个活跃的研究领域，持续近三十年。它涉及从电流和电压测量中估计转子速度和/或位置。本文从无传感器控制的角度探讨电动驱动的可观测性条件。此类系统的模型具有很强的非线性。为此，采用局部可观测性方法来分析某些工况下无传感器驱动性能的退化。通过扩展卡尔曼滤波器作为观测器，用数值模拟和实验数据验证可观测性条件的有效性。
英文摘要：
Electric drives control without shaft sensors has been an active research topic for almost three decades. It consists of estimating the rotor speed and/or position from the currents and voltages measurement. This paper deals with the observability conditions of electric drives in view of sensorless control. The models of such systems are strongly nonlinear. For this reason, a local observability approach is applied to analyze the deteriorated performance of sensorless drives in some operating conditions. The validity of the observability conditions is confirmed by numerical simulations and experimental data, using an extended Kalman filter as observer.
