本文报道了一种交流电机无传感器控制方案的实现，它既不需要模型观测器，也不需要测试信号。该模型是基于凸极检测，通过使用基本的PWM激励和PWM电压矢量引起的线电流的导数的测量。转子位置的推导在低速和零速度下是可能的，而无需单独的测试信号，并且在高速下也是可能的，而无需机器模型的知识。实验结果表明，完全无传感器感应电机控制在低速和高速验证了这种方法的原则
This paper reports the implementation of a sensorless control scheme for AC machines that requires neither a model observer nor a test-signal. The model is based on saliency detection through the use of fundamental PWM excitation and the measurement of the derivatives of the line currents induced by the PWM voltage vectors. Derivation of the rotor position is possible at low and zero speeds without separate test signals and also at higher speed without the knowledge of the machine's model. Experimental results showing fully sensorless induction motor control at low and higher speeds validate the principle of this method
