    摘要： An apparatus, system, and method are provided for simulating outputs of a resolver. One apparatus includes an adjustable sine waveform generator for simulating first and second sine wave signals, and an adjustable cosine waveform generator for simulating first and cosine wave signals. The apparatus also includes an adjustable waveform generator and an adjustable gain circuit coupled to the sine waveform generator and cosine waveform generator. The system includes a device simulating a resolver coupled to a motor controller. The device includes an adjustable sine waveform generator and an adjustable cosine waveform generator coupled to an adjustable waveform generator and an adjustable gain circuit. One method includes transmitting a signal simulating at least one resolver fault condition to a motor controller to determine if the motor controller detects the fault condition(s). If the motor controller fails to detect the fault condition(s) and/or transmit an error message, the motor controller is malfunctioning.

    摘要： A method includes detecting a first event and executing a first procedure to identify a sensor offset in response to detecting the first event. The method further includes determining, via a computing device, whether the sensor offset was measured during the execution of the first procedure, scheduling a second procedure to execute in response to detecting a second event if the sensor offset was not measured during the first procedure, and scheduling the first procedure to execute in response to detecting a subsequent occurrence of the first event if the sensor offset was measured during the first procedure.

    摘要： Methods and apparatus are provided for detecting a phase current sensor fault in a multi-phase electrical motor. The method comprises, receiving an input torque command T* and measuring a set of feedback signals of the motor including a phase current Ix for each of the phases of the motor, generating direct and quadrature command phase currents Id*, Iq* for the motor corresponding to a value of the input torque command T*, determining a total command current Is=[(Iq*)2+(Id*)2]½, generating a negative sequence current Ineg, where for three phases Ineg=(⅓)[Ia+(α2)Ib+(α)Ic], where α=ej2π/3, combining Ineg and Is to provide a normalized negative sequence current Inn=Ineg/Is, comparing the normalized negative sequence current Inn to a predetermined threshold value INN* to determine the presence of a phase current sensor fault, and executing a control action when Inn>INN*.
